Transformers

Hello everyone,I am a beginner when it comes to FME and loops. I have the following task: I have an attribute column with a value. (e.g. Person 1, age 18Person 2, age 35Person 3, age 41Person 4 , age 45The age column should now be increased by one value x times per specified loop run. The number of loop runs should be controlled using user parameters and variables.I am using FME 2022. Can anyone help me? I have found examples with loops, but as a beginner I don't understand them.Thank you very much for your support. I look forward to your reply.A.B.

When upgrading from one version of FME to the next, I can upgrade some upgradeable transformers, and I can also upgrade the readers and writers to the latest version. But what about the readers that are called by the FeatureReader (and writers by FeatureWriter)?We just upgraded from 2024.1 to 2025.1, and I upgraded the FeatureReader transformer reading a geodatabase. Does upgrading the transformer, upgrade the GDB reader functionality? Or does it automatically call the latest GDB reader? Or does it stick with the old?

EDIT - I have solved my own issue here! We had some network changes, and I needed the SAS from the top level of the storage account rather than the specific container. Problem solved. I’ve successfully connected to the Azure BLOb using 2025.1 Form using the AzureBlobStorage Connector:I can connect to the “Hosted” folder inside the container “shared-data”. I am connecting using SAS. However, I need to use Flow 2024.2 and so I need to open this same workbench in Form 2024.2…. and this is where the fun starts!The transformer is slightly different, when I try to configure the Container I don’t seem to have the option to add the “Shared-data”.

A caseA column code contains both unique and identical values ​​(e.g., A, A, B, C, C, C, D, E, E).A second column names contains different names.I want to group a column, but the names associated with it need to be merged.How can I easily solve this in FME? Thanks in advanced!

I have a column containing values ​​(contains 1 or more sorted names) that are both unique and duplicate. Now I want to assign a unique number to each value. This means that the values ​​that are the same should also have the same unique number. How can I handle this within FME? Thanks in advance!

I am trying to connect to a SFTP using the FTP caller. I have followed the instructions in https://support.safe.com/hc/en-us/articles/25407554321805-Using-a-Private-SSH-key-with-FTPCaller-to-Authenticate-an-SFTP-Connection-for-FME-Form-and-FME-Flow-on-Windows-Systems and I can connect to the server using other methods (winscp, filezilla) so the new key is working. In the log (with debug enabled) I get the following:SystemCaller: Executing 'start "" "C:\Program Files\PuTTY\pageant.exe" --encrypted C:\PPK\PrivateKey.ppk'FTPCaller (FTPFactory): Using the 'SChannel' TLS library for HTTPS/FTPS connectionsFTPCaller (FTPFactory): FTP info:   Trying ??.??.??.??:22...FTPCaller (FTPFactory): FTP info: Connected to ??.??.??.??

Hi All, I have the following set up where / separate's attributes - where Value X and Y can exists multiple times within a month linked to the Item ID.Place / SubPlace / itemID / Year / Month / YYYYMMDD / ValueX / ValueY /  SUMXPlace / SUMXSubplace / SUMYPlace / SUMYSubplace /What i would like to do is after i have the sum per month per place and subplace, is to see the sum again of these sums on a quarterly basis - ie. Jan-Mar = Q1, April-June = Q2.So the final table would be something along the lines of this - to still allow filtering per place/subplace/quarterPlace / SubPlace / Quater / QSUMXPlace / QSUMXSubplace / QSUMYPlace / QSUMYSubplace /Any ideas or help would be greatly appreciated!/Emma  

Hello, I have a question regarding the DGN Reader/Writer about reading and writing external reference files.I am using the DGN Reader that contains a reference to another DGN file. In that referenced file there is a rectangle (an igds_shape element). In the DGN Reader parameters I enable the options "Read Elements From Reference Files" and "Keep Elements That Represent Reference Files".My goal is to move that rectangle to a different location and save it into a DGN file in such a way that:the rectangle appears at the new (correct) position - this part is not a problem; I already have a workbench for moving the geometry but it still keeps the link to the original referenced DGN file, and the referenced DGN file itself remains unchanged.In other words, I want to move the geometry in the main DGN while keeping the external reference link attached to it, so that any futur

Hi, I’m working on a script which copies data from an Esri arcsde geodatabase to a postgis database. I need to know if the table in the arcsde geodatabase is versioned before I run the rest of the script, and I have a pythoncaller which runs something like this (simplified here):layername = "schema.layerName"connectionFile = "path_to_connection_file"arcpy.env.workspace = connectionFiledesc = arcpy.Describe(layername)isVer = desc.isversionedfeature.setAttribute("versioned",isVer) self.pyoutput(feature)Now, I don’t want to type in the path to the connection file manually, but rather obtain it by some function which can collect the data from the list of database connections I entered in the settings. Is this possible? I’ve looked into the FME Web Services API reference for such a function without any luck. Best regards,Jacques 👷🏼 

One of the greatest new features of the IFC4x3 schema is that we can write 2D lines to IFC, which was not supported in IFC2x3.Why does the new IFC writer support only 3D surfaces and solids and not 2D line geometries? 

It seems that in the iOS18 update Apple made changes to the HEIC file container that means the FME Feature Reader using HEIF (High Efficiency Image File Format) now fails to read the HEIC files.We are currently using FME 2022.2.Is there a later update that will support iOS18 images? Is there an alternative way to read in these images successfully? 

I'm trying to setup the children and parents list attribute for export to CityJSON. Therefore I thought to use the listbuilder, but I get a different result than it should be. This example is how it should be: And this one is my result. It looks like there is an extra layer in it.How can I solve this?

Hey all, Currently having an issue using the ArcGIS Connector when using FME Flow (or Form without Feature Caching / Counting on), receiving the following error below. Full log posted below the error message. The outcome I am looking to produce is to update a CSV file hosted on an Enterprise Platform. This does run with form with feature caching on. Any help would be much appreciated.Thanks. Ash135 2025-11-14 17:25:19 | Message Type: fme::internal::_v0::py::Exception 136 2025-11-14 17:25:19 | Python Exception <TypeError>: Call to pyoutput() requires an output_tag argument when multiple output ports exist 137 2025-11-14 17:25:19 | Error encountered while calling method `input' 138 2025-11-14 17:25:19 | ArcGISOnlineConnector_2_CALLER (PythonFactory): PythonFactory failed to proc

Hi Everyone!I’m currently working on a workflow using a dwg file (water system) to convert it into a geodatabase. I was wondering if anyone has any tips on the transformers and workflow I could use to successfully do this? Right now I have my dwg reader as individual types, leading into an attribute filter, and geometry filter (3 different ones- 1 for water, drainage, and sanitary). These 3 end up writing into the geodatabase. I would like to have feature datasets separating water, drainage, and sanitary written in the geodatabase. I understand this is a big undertaking, but any tips (or perhaps links to guides) would be extremely appreciated! Thank you!

I have a job that downloads 7 text files from an FTP directory, and for the last 3 days, 6/7 files have downloaded but 1 always fails (the same one each time) with the error: Number of redirects hit maximum amountI am aware of the post below, but as no similar setting exists on the FTP caller, I’m lost. I can upload fine, and manually downloading the files by logging into the FTP site, or using a WinSCP script also works. The file that failed today was empty (0MB), but so are some of the other files it downloads, and yesterdays file had records and still failed. Empty files are not uncommon for this job, and it has never presented an issue before. This has started occurring since upgrading to 2025.1.3 from 2022, and occurs on both FME Flow and Form. This error has so far not ap

Hi  I have spent far too many hours trying to make the change detector dynamically pick up changes. The scenario is: I have 10 datasets that need to be compared between the original and updated databases. Each dataset has only a few fields that need to be checked for changes. These fields are different for each dataset. I have a CSV which is acting as a 'config' file and contains a list of the field names to check for each datasetI have 2 workbenches; the first workbench gets all of the information from the config file, then passes through the information via user-parameters to the Change Detection workbench via workspace runner. Even though I have created a user parameter for the "Match Selected Attributes" config in the ChangeDetector, I can't pass through this information via the workspace runner. It ONLY works if I run the Change Detection workbench individually, and this isn't linked to the

Hi, sometimes the XML Driven XML Writer decides that I have not set the Application Schema when I click on FeaturePaths edit button. As you can see it is set and the XSD file behind works well in a different workspace. But for some reason I get the error you can see in the attachment and I don’t know why. Starting a workspace from scratch works again with the same settings. Thank you for advice.

Hi everyone,I’m working with DWG files in FME — reading them, attaching XREFs, and then writing back to DWG.I’m trying to attach an XREF to a specific layer (something other than Layer 0), but so far I haven’t had any success. I’ve tried setting both the fme_feature_type and autocad_layer attributes, but the XREF still ends up on Layer 0.It also seems that when using the DWG reader, FME always interprets XREFs as being on Layer 0, even when they’re on a different layer in the source DWG.Has anyone found a way to preserve or specify the layer assignment for XREFs when reading/writing DWG files in FME?Thanks in advance!

Looking at the new Define Read Criteria By: Custom Query option in the FeatureReader in 2025.1I feel like there should be a warning against using Define Read Criteria with Esri Geodatabase format as it uses sql and bypasses specific SDE functionality. 

We have a polygon shapefile in which features overlap because the data is self-reported. During our analysis, we noticed that when a feature is 100% overlapped by another, it is not considered in the clip process with another dataset. However, we want all features—even those that are fully overlapped—to be taken into account when performing the clip. What configuration or procedure should we use to ensure this behavior?

Hi FMEers, I’m trying to create a basic map using the HtmlReportGenerator. I’ve added 2 polygon hosted feature layers from our ArcGIS Enterprise Portal, that are comma separated in that URL field. They are shared with groups that I am a member of so I have access to view them.When I send it through to an html writer, the output map is blank. I wasn’t sure if that was because it is offline so I also published to FME Flow but it’s still blank:  I also tried with a layer shared to public from our portal with the same results.Is there something I’m missing from the docs?

Hi guys,how can i handle to read in Excel sheets (with other column names from time to time) and have the possibility to choose from a schema (xls) the right attribute names for the workflow…..Parameters on the reader?I’ve tried the Attributemanager and import a excel file...but the names from the excel sheet are only added to the default output attribute names a dropdown list on the Output Attribute name would be great……..any help to handle it or a link to another articleGreetz and thanksFranco

I have the following table, very simple:DATE_START ID 19921101 0502010000013950 19950209 0502010000013950 20031231 0502010000013950 20040115 0502010000013950 20040120 0502010000013950 20110704 0502010000013950

This issue seems to appear again in FME 2025.1!
