Python global function definition and reuse in many pythoncaller

I wanna be able to define a global python function (perhaps in the startup scirpt?) like this:def dosomething(number)new_number = number + ... doing something with itreturn new_number then, en would like to reuse this global function many times at different moment in my workspace on many different attributes that has to go through the same treatment. During the workflow of data_a, I'd call a pythoncaller this way:newNumber = dosomething(feature.getAttribute('num_1'))feature.setAttribute('num_1',newNumber)newNumber = dosomething(feature.getAttribute('num_2'))feature.setAttribute('num_2',newNumber) During the workflow of data_b, I'd call a pythoncaller this way too:newNumber = dosomething(feature.getAttribute('num_a'))feature.setAttrivute('num_a',newNumber)newNumber = dosomething(feature.getAttribute('num_b'))feature.setAttrivute('num_b',newNumber) I tried the same using a pythonCaller inside a customTransformer, but

Trying to understand best approach for project using FME. FME Form or FME Flow Automation? Related to creating 3D Buildings

Hi All, This post is primarily seeking guidance, or advice rather than answering a definite question. I am trying to figure out the best method to automate 2D files into 3D buildings and load them into an SDE database buildings table. Though possibly also receiving 3D files from said developers.  These files would be received by planning from developers and planning would share them with GIS (me). Would an FME App work better? Can it be dynamic and recognize all sorts of 2d or 3d files? Do I need a separate FME app for each file type? I created a PDF document that I want to share to my planning team so that developers can abide to for my future automated process. from my understanding, it should work, but I've noticed the tutorials (that use CAD) have an accompanying CSV with the building info. This has casted doubt on how i envisioned on using FME. I am very open to criticism as I am very green with FME still.

Access denied when fanning out many folder based dataset

I have a long workflow that transforms some DWG (for buildings), GeoTIFF (for terrain) and FBX (for trees) in 3D datasets (IFC, OBJ, FBX, glTF). The whole process takes a bit more than a day because it's on a quite huge input dataset. The output is fanned out based on a 500m x 500m grid.When I was testing my workflow on a smaller dataset, it worked fine on the four different file formats. Now that I tested it on a bigger dataset, it only works on the file based datasets (IFC and OBJ). The workflow is still able to write the first part (terrain) in the folder based datasets (FBX and glTF), but as soon as it starts writing the buildings in the all ready created fanned out folders, I get an Access Denied (that I didn't get when I was working on smaller datasets).Does anybody have any idea why ?

Can I import a custom python package from an azure repo into FME?

We have a custom python package project sitting in an azure repo, with build pipelines. This python package can be built on multiple python versions 3.8, 3.9, 3.10 with the help of the Hatch third party package. One of the pipelines produces an .whl artifact for the project, can this be used to install the python package locally on any machine, and simply point FME to this package? I don't really know all the intricacies associated with this approach, if it is possible can you please take me through the steps to achieve this or point me in the direction of a detailed article, any help will be appreciated

Dynamic reader schema mismatch for '@Value(ENCODED,fme_feature_type)'

The workbench I am putting together contains a feature reader to a dynamic write in several locations.  The workbench itself detects shape files in a folder location, validates projection, geometry and AssetID attributes. Then writes out any identified errors to a shape file for upload in another step.The dynamic write of the "errors" shape file works however the dynamic write of the upload file encounters a warning where the below appears in the log: Cannot define schema for '@Value(ENCODED,fme_feature_type)' as the feature does not contain schema information. While we have the schema mismatch the remainder arrive correctly.The features arrive with the new layer name that I want to use. Testing my workbench I have found that the dynamic writer performs as expected (and outputs the shape file) for every stage up to exposing the fme_feature_type, mapping the new layer name and setting the dynamic reader to the new layer name.I have tested this in the latest version (20

Translation was Successful then Translation Failed

I have some FME translation files (4 or 5 of them) that I use regularly on different datasets. These have worked without issue for some time, and are still working now except for one strange thing that's changed. The process runs, ends with "Translation was Successful" in the log as normal, then about 5 seconds later "Translation Failed" appears in red.  As far as I can tell everything has worked fine, there are no errors in the rest of the log (usually if it fails I get good detailed error messages to help me fix my data problem). I think my data is good to go. But I'm not sure why I'm getting this delayed "Translation Failed" message in the log. One of the blue warning type messages (so not an error) says that my ArcGIS Pro v3.2 isn't supported, but this isn't shown as an error and my data appears to be translating fine. I think this ArcGIS Pro update is the only recent change that might affect FME though, so is that the culprit?

Is there a way to get different counts from a merge to write them to a Database?

I have a work bench that transforms data from multiple sources and then inserts only the new records from the combined data into a table using a merge transformer and Feature Writer. For auditing purposes I need to log how many records were written to a table in the same Database as well as pass that info back to FME Server to include in a email via automations. I am able to do this currently with the summary output of the Feature writer, however I would also like to pass the count of the existing records and also set the total written to 0 rather than the undefined that gets returned when there is no new records to add. I've tried using counters but either I'm using them incorrectly or I'm missing some steps as the flow doesn't continue down the path when there are no new records.

Creating 10x10m random plots that occupy 20% of an area

I'm looking for some advice to get me started on creating a workflow. I'm an intermediate FME user but this problem has got me stumped! I'm dealing with roughly 100 areas that require tree planting. Each planting area will be a different size depending on the environment. Once each area is planted, we need to monitor 20% of the area to determine the success rate. The monitoring plots are 10 x 10 metres, so area of 100 sqm. The plots need to be placed at random and I need to find out how many monitoring plots can be fit wholly within a planting area where the total area of the plots is at least 20% of the total planting area. For example, if the planting area is 3000sqm, I would need to assign 6 x plots.20% of 3000 is 600. 600sqm would be 6 x plots. Any help or advice would be appreciated.

Error trying to connect ESRI mapservice with "Esri ArcGIS Feature Service" Reader.

Hi, When i try to connect open service: https://gis4.waimatedc.govt.nz/arcgis/rest/services/Public/RoadClosure_Waimate_Active_Planned/MapServer using "Esri ArcGIS Feature Service" reader, I get Python exception error. There is no authentication required as its open service. The fact that I can use HTTPCaller and get the data with query service tells me, this service doesnt require authentication. Am I missing something? I tried few other rest service from this council with no luck. Python Exception <HTTPError>: 403 Client Error: Forbidden for url: does this error means anything to do their IT system infrastructure? Any help would be appreciated? Cheers,

I cleared several times my temp folder with ClearTemp.cmd, also Purge temporary files in my FME-script. But still I have problem with temp-file! Can you guide me how can I fix the problem? Thanks I can read my file via Reader and there is not any problem, but when I read it via FeatureReader, I have problem with temp file!

How would we set the topology builder to allow traffic from segment A to B, A to C, B to A or C to A, but to not allow traffic from B to C or C to B?

ESRI File Geodatabase Open API Read Only Error across Server/Network

Hi all, Something very strange happening just wondering if anyone has had the same issue. I have a process that both reads and writes ESRI Geodatabases. In recent weeks I have noticed that every time I try and read in a geodatabase I get an error "Workspace or Data Source is Read-Only". I have checked my permissions, I have checked I am the only user accessing and all is fine, and the error disappears if I copy the gdb locally - this error only occurs when reading across my work network between servers - but I 100% have the correct permissions for the task. To add to the complexity, the error only happens about 90% of the time but on the odd occasion all works as intended. Anyone any bright ideas? Cheers,Jack

Creating WFS in FME Form and/or FME Flow

Hello Forum, For a project I need to create WFS feeds for several datasets. Looking at https://community.safe.com/s/article/how-to-create-a-wfs-service-using-fme-server I see that this may be possible. I’ve opened the example workspace provided in https://community.safe.com/s/article/how-to-create-a-wfs-service-using-fme-server. It wouldn’t open in v2023.1, so I opened in v2021.2 instead. Is creating a WFS in FME Form really this complicated?…  Or is there a more straightforward way of creating one? I have FME Form and FME Flow. Are there other pre-requsistutes I need to consider? Note that at the moment I do not need the WFS to be externally accessible. Access should be internal only for the moment. Thanks,Stuart
