FME Form

Hi, I want to import the WFS service from Digitaal Vlaanderen, specifically the address registry, but my FME only imports a maximum of 10,000 features.I had found that it was possible via paging, but apparently that is no longer supported, or at least I can’t find it. It should then be done via loops, but I’m stuck. I found that it should be possible using an HTTP caller and JSON fragmenter, but I’m already stuck with my HTTP caller. Could someone help me set this up correctly? The URL is https://geo.api.vlaanderen.be/Adressenregister/wfs?REQUEST=GetCapabilities&SERVICE=WFS      

I have attempted to use the NeighborFinder transformer to achieve a one-to-many join; however, it is not producing the expected results.In my case, the base dataset contains values such as 30,511 and 55,867, and my expectation is to match all records where the base value is greater than 30,511.Since NeighborFinder does not seem suitable for this requirement, could you please suggest an alternative transformer or approach to achieve this condition-based matching?Thank you. 

Hello, I am currently working on adding data (a source file in Geopackage format containing point and polygon tables) to our Oracle enterprise database. I am using a dynamic workspace to process the data and an external table (CSV file) to define the required schema in the FeatureWriter. When writing the data to the database, three additional attributes (not defined in my schema) were recorded. They are called “rotation”, “textstring” and “height”. After some research, I realised that these are likely linked to the following FME attributes: fme_rotation, fme_text_string and fme_text_size and that this is related to the “fme_point” geometry. I have tried several ways to remove these attributes but have not succeeded (exposing the attributes and removing them before the writer, telling the writer not to write them in ‘attribute to remove’, writing the tables containing polygons and those containing points separately in different writers.Do you have any idea

Hi FME gurus. I am trying to extract values from a list to populate columns with the associated values in the fields.  In my list (called _columns) I have a caption field which has the name of the column I want to create and the date value I want to populate into the field so the example I have in the screenshot I want to look like this: Application ID Last Inspection Next Inspn Due 648343 2025-06-23 2026-06-16 15456.. 2025…. 2026….  The list exploding only brings out the name of the original column ‘caption’ but I am looking to use the values in the list itself to build the attributes and populate the values. There are rec

Good day,I have a table with a couple of records.I would like to keep one record per category and this record should be the record which has the less attributes with a null (missing) value (I highlighted them in green on the screenshot.). How can I automatically calculate which record per category I should keep? 

Hi.As most will know, Geopackages are notoriously sensitive to geometry topologies.I want to insert all polygons into a single layer/table, but the topology is tripping me up.I have a number of fairly simple polygons (fme_polygon and fme_donut) and a handfull og more complex polygons, e.g. large polygons with many holes. These latter polygons are stored in FME as fme_aggregate for some reason. The holes are all created by the Clipper transformer.I’ve successfully coerced my simple polygons into fme_aggregate’s, but when output to Geopackage, some of the geometries gets deleted and the feature is stored without its geometry. This typically happens to the unaltered geometries (i.e. the original fme_aggregate’s).I’ve checked that all the input geometries to Geopackage are valid and has @GeometryType() = fme_aggregate, so what’s tripping me up here ?Any insights are welcome.Cheers.Using 2025.1.1 for this.

Within the new ArcGIS Feature Service reader (part of the Esri ArcGIS Connector Package) if you choose a source type of Enterprise it’s not possible to connect to a feature service that is shared across an entire organisation and not in a group.This can be done if you use a Source Type of Standalone Server (but it’s not obvious).It would be nice to have and Item Source of Organisation which would allow connection without specifying a Group 

When using ArcGIS Feature Service (reader, writer, featurereader, featurewriter) I am only able to reference items using Folder and then featureservice name + itemid (in paranthesis after the name). Is it possible to directly refer to a service using only itemid?(for my case the data is hosted on my institution’s AGOL)

I’m creating a workspace that reads 7-8 tables from a file geodatabase and then writes them into tables in a SQL database.  One of the tables is sometimes present and sometimes missing (that is expected).  I need to create a workflow where when the table is present we write the data into the SQL table and when it is not present we just truncate that same table in the SQL database.  I currently have a gdb reader connected to a tester that passes when fme_feature_type Like MSAG_To_RCL_Synchronization. This works when the table is there but when it’s missing the reader just closes and gives the message “The table name 'MSAG_To_RCL_Synchronization' could not be found in the Geodatabase as either a feature class or a table” and closes before any input gets to the tester. Any ideas on how to conditionally test if a table exist or not and then either write the data or truncate a SQL table.

It seems I have no place to force FME to include the code_verifier parameter in the request body to obtain a token (see requirements below). Any ideas of how to work around this in FME? The postman equivalent is selecting the grant type as "Authorization Code (with PKCE)". I can use the same challenge and verifier more than once, just need to include it in the body rather than a querystring.  Per the platform's API docs: Parameters sent in Request Body, Form-URL Encoded. (cannot use JSON or querystring)code=<code received in callback url>client_id=<Application OAuth Client ID>client_secret=<Application OAuth Client Secret>grant_type=authorization_coderedirect_uri=<User redirect URL (from step 4)>code_verifier=<User Generated Code Verifier>  

Hi all.I just experimented with a small workflow, that scans a folder for files, and attempts to read those files using the generic format.I tried with CSV and DGN, and both worked well.I then tried with Geopackage, and then it blew up.First because FME’s guess using the extension was wrong, so I had to parametricize the format used.Then it blew up with an internal error message (“Too many recursive macro substitutions”):2026-03-03 15:14:24| 2.6| 0.0|WARN |UniversalReader -- readSchema resulted in 0 schema features being returned2026-03-03 15:14:24| 2.6| 0.0|ERROR |Too many recursive macro substitutions -- line currently is: `SOURCE_READER GENERIC REAL_FORMAT "$(REAL_FORMAT)" EXPOSED_ATTRS "$($(FORMAT_SHORT_NAME)_EXPOSE_FORMAT_ATTRS)"'2026-03-03 15:14:24| 2.6| 0.0|ERROR |class stk::ex::UString<0> __cdecl tabrdr::ClassicTableReader::macroSu

As the title suggests, I’m having an issue when running FME (2022.2) from the command line. I’m clipping several LAZ files with a polygon grid, and FME automatically puts the output files in one folder per LAZ file. I’m technically fine with this behavior as I was going to fan it out anyway, but the extension is included in the folder name (e.g. FILENAME_1.laz), which the following processing step in my pipeline cannot handle.  The problem only occurs when run in the command line. Is there any setting anywhere so that I can get rid of the file extension in the folder names? 

I have the exact same issue as is described here: That topic is closed, so I'm starting a new one over here. I got the error “Check the geometry of such feature is valid and is not too small for the resolution”, while updating a feature. I use FME Form and Flow 2025.1.2 and ArcGIS Pro 3.3.1 with ArcGIS Enterprise 11.3.At first I also thought the issue only occurred in FME Flow, not in FME Form. But now I'm checking the issue again and it is also in Form.In my case I use the ChangeDetector to check if the feature exists and if so if it is changed. If it existed and is changed, I'm also using the Update Mode in a FeatureWriter. I tested with not updating the spatial column, but that didn't make any difference. I still got the error. And I am positive the geometry didn't even change: setting the ChangeDetector to only check geometry sends the f

​Hi everybody, I have a similar issue to the one the creator of this thread has: The difference is that I'm dealing with donuts. The workaround from Takashi (buffer issue location → dissolve → aggregate) doesn’t work with donuts. The reason why this doesn't work is explained here: The GeometryValidator reports self-intersections in the wrong place for donuts. If I buffer the issue location, part of the donut that doesn’t need to be buffered gets buffered, and the actual issue location remains a problem. I also tried the GeometryValidator repair function, but this didn’t work either. 

I have a donut geometry (see WKT below) which I am trying to validate. Using the GeometryValidator only looking for self intersections I get an error on the start/end point of the outer ring: Error report:Coordinates from the inspector: I would expect this to not be reported as a self intersection since polygons normally require intersection at exactly that point.  Why is FME reporting this? I have tried using both FME Desktop 2021.2 and 2022 beta. Geometry WKT: POLYGON Z ((558000 6142955.0838 0,558000 6142917.0404 0,557997.11 614

In Form v2026.1, what exactly does the new option “Read Best Fit View if Selected view is Missing” do? The “Help” says:“This parameter controls reader behavior if a selected view is missing.By default, if a view specified in the Specify View to Read parameter is missing, the reader selects the next available view.”Does it select the very first view that pops up when clicking the 3 ellipses (...) or is it referring to something else?Was that option a hidden feature in previous versions that got exposed as a parameter in 2026.1?

Hello I have FME 2022.2 version and i also could upgrade it to 2025 if it helps but i would like to extract data  Input data : *.pts or *.e57 file format (about 2 to 5 room point cloud data in One *.pts file/*.e57file)Desired output data : *.pts file format (ONLY 1 room to be extracted in *.pts file format)Other supporting data : Sitewide room model in *.ifc format (federated model having about 20+ rooms in 1 IFC format) TASK : Using IFC room model for any give Room for example (Room1), i would like to clip the input data set i.e. in *.pts/*.e57 file format and out only that particular room  (Room1) *.pts format data.  Am not sure how to set / which reader and writer / transformer to use to get it right . I understand i will have to use Clipper to clip *.pts file using IFC file somewhere. Highly appreciate and obliged with workflow for your support and know-how. 

I am exporting a large dataset to Geopackages divided into municipality, county and nationwide datasets. Only for some of the largest ones I get errors like this: 2026-03-14 21:22:05|3087.0| 4.4|ERROR |OGCGEOPACKAGE writer: sqlite3_exec(DETACH DATABASE "temp_rtree_48b1c18db46d5df6f87d84127b4186ce") failed: database temp_rtree_48b1c18db46d5df6f87d84127b4186ce is lockedAs far as I can see, the produced geopackage works fine and the content is complete. But an additional file is left together with the zipped geopackage file.The full file name of the extra file is something like Basisdata_0301_Oslo_25832_FKB-Gronnstruktur_GPKG.gpkg.tmp_rtree_bunnsjikt.db. Have anyone else seen this? Could this be related to some kind of size limitation of the Geopackage/SQLite format? Are there any workaround or solution? The FME version

Hi all, I regularly setup workspaces with quite a few feature readers & writers that need a lot of parameters changed when moving between environments. I make use of scripted parameters to make this easy based on an initial Environment selection.The one parameter I can’t get to update correctly with a scripted parameter is the web connection, does anyone know if this is possible?

Has anyone else experienced this? I'm using FME 2022.2. If I pick an attribute from the arrow drop down menu, it inserts it in the DateTime Attributes field as @Value(CREATETIMESTAMP). When the transformer runs, it doesn't convert the value. But if I select the attribute from the 3 dots menu, it's fineIn the 3 dots menu chooser, there are sort of two sets of the attributes....

Hello everyone,I am having difficulty correctly assigning a spatial reference to GOES satellite imagery (Band 13) stored in NetCDF (.nc) format when working with FME Flow 4.0 / FME Workbench.Environment•Product: FME Flow 4.0•Workbench: Yes•Data type: GOES satellite imagery (ABI sensor)•Band: Band 13 (Infrared – Brightness Temperature) Full Disk•Format: NetCDF (.nc)•Satellite: GOES (GOES‑16/18/19 – ABI)Problem descriptionThe NetCDF file opens correctly in FME, and the raster data for Band 13 is read without errors. However, no coordinate system is automatically assigned, and I am unable to manually define the correct projection in a way that allows proper georeferencing.I understand that GOES ABI imagery does not use a traditional map projection (such as EPSG:4326, Mercator, or UTM). Instead, the data is provided in the so‑called ABI Fixed Grid / Geostationary projection, where pixel positions are defined by scan angle

Hello,  it is possible to see a FME workspace CPU usage at the end of a job in the logging. However, when you activate a stream it will occupy an Engine and it will not give CPU usage in the logging. Is there a way to find or register the CPU usage of a stream that runs 24/7?

Hi all,I am experiencing an issue with dataset fanout in my workbench after upgrading to 2025.2.0.0 with Build 25810 (WIN64). The workbench worked perfectly in 2024.2.The workbench reads in a FGDB file 30,000,000 features using a reader, then performs spatial filtering with coordinate grid tiles and fanout into geopackage files according to the tile names using a writer. The workbench always stopped while outputting the first geopackage file with the following error message.  Insufficient memory available -- error code was 2 - please read the FME Help section 'Adjusting Memory Resources' for workarounds.The workbench worked fine when I set the max features to read in the reader as 100,000, but the writer failed once the reader read all 30,000,000 features. I tried lowering the number of features per transaction in the writer but it did not work. Is anyone else experiencing a similar memory issue with dataset fanout in 2025.

Hello everyone,I have a workspace app that converts a .dgn file to a .gpkg An user tied to run the tool with a dgn file, but he received a failure message. I looked at the job and I saw the following errors 464 OGCGEOPACKAGE writer: Invalid curve: not enough points 754 OGCGEOPACKAGE writer: Invalid curve: not enough points 872 OGCGEOPACKAGE writer: Invalid curve: not enough points 957 OGCGEOPACKAGE writer: Invalid curve: not enough points 1051 OGCGEOPACKAGE writer: Invalid curve: not enough points    Did anyone have similar errors and what can I do to solve these errors?

There are a series of similar posts but still not seeing a way to expose attributes dynamically.I have a a large number of geodatabases which have multiple layers and different attributes, which I am merging with a geometry layer so I end up with a single layers with lots of attributes.The geodatabases have a series of tables and a geometry layer, but there is no consistency in attributes between the geodatabases.How do I expose and have these exposed attributes output to a merged dataset?
