FME Form

Hi everyone,I'm working with a topologically accurate line network in FME 2023.1.1.1. I have:Two source points located at the start points of some lines (also refer to pipe-network_plus_point-features.png)→ the blue rhombusValves represented as point features, located somewhere along the lines (not necessarily at endpoints)→ the magenta colored pointsMy goal is to identify all topologically connected lines starting from each of the sources and continuing until the valves are reached. Each group of connected features should be treated as a separate subnetwork. In this case, I expect to identify two distinct subnetworks, one for each source. Also refer to desired_result.png and the detail 1 and 2.Has anyone tackled something similar? I’m looking for a solution that ideally avoids using Python and relies on standard FME transformers (e.g., using loops or topology-based logic).Any suggestions or best practices would be grea

Hello all,is it possible to use one AttributeRounder to round different attributes to different accuracies?Let’s assume i have two attributes, A and B. I want to round A to 2 decimal places, whereas i want to round B to three decimal places. Is this possible with one AttributeRounder or do I need to use the AttributeManager.Cheers!

 I have a parent WS that runs a load of WorkSpaceRunners. I want to pass on some User Parameters from the parent to the “kids”, see settings below. The child workspace is already setup with these User Parameters and run fine with them when run on their own. I have not been able to find any documentation on this, so the settings below are my best guesstimate. My steps are User Parameters in parent -› User Parameters in workspacerunner settings -› User Parameters set up in child workspace settings -› use them in child workspace.So, how do I fix this?Does the child WS need to be set up in a special way in order to pick up the incoming parameters? Is there a misstake in the syntax? Anything else I can look into?  

I'd like to understand what this error means in the following context and how I might go about resolving it. I have a workspace that works perfectly fine if I run using cached features up to transformers just prior to a FeatureMerger then run from the FeatureMerger to a writer. However, when I try to run the entire workspace it results in an error that aborts the translation at the writer. I've also tried many other methods of joining these 2 streams and all are resulting in the same error output. MULTI_WRITER: No MULTI_WRITER_TYPE{*} or MULTI_WRITER_TYPE{3} was specifiedIt seems like I need both streams to be ready at the FeatureMerger at the same time but I have not been able to gain control over execution order or block passthrough features through a variety of attempts. The goal is to read from both a CAD model and a DB, then compare the two datasets on a unique key, then write an SQL statement to a text file or SQLExecutor. I've only

No bookmark navigator in 2024.2Bookmark navigator in 2023In FME 2023.2, there was a "Show Bookmark Navigator" checkbox under Tools → FME Options → Toolbars.In FME 2024.2, this option seems to be missing on my system. We're in the process of switching versions and noticed it's no longer there.I use this feature frequently to quickly navigate between bookmarks in large workspaces.I've attached two screenshots showing the difference between versions.Has this functionality been removed, renamed, relocated or is this a bug?Thanks in advance.There is no additional detailed info in the docs:

HiWe are migrating from one AGOL portal to another (with regional hosting). I have used the AGOL connector to list all service definitions of hosted feature services, download/upload the .sd files and publish the service on the new portal. This appears to have been successful.However, I am now trying to compare the feature services in each AGOL account and am struggling. I want to iterate through each feature service and compare it with the the one on the other account using the Change Detector. I have used the AGOL connector to list all the feature services and fed that into a feature reader. Unfortunately, all the features just come out the generic port without any schema so it seems impossible to compare the feature services. Does anyone know a way this could be done please?Also, I need it to finish with one feature service before it moves on to the next one. Is this possible?Many thanks 

We've set up a process for a client that takes data and writes it to CSV. That CSV is then loaded into a data warehouse.That CSV conforms to the official CSV standards and thus the last line ends with a CR/LF:Shown here in Notepad++. This means there's a last, empty, line in the file. The data warehouse system apparently cannot handle this. Is there a way to remove this last CR/LF from the file? (post-processing python, probably).I must admit I am not convinced this should be fixed on the FME side, but trying to get the data warehouse developers to move on this is not going to happen.

Has anyone else had any issues with the SubstringExtractor in FME2025? I have a process that works in an older version (2021) but in the 2025 version I am seeing a different behavior.Wanting the last 7 characters in a string I used a Start Index of -7 and an End Index of -1. This worked in FME 2021. When opening the workspace in FME 2025, it initially works, but when I upgrade the transformer from V2 to V3, it then returns no value. I created a new blank workspace and added a brand new SubstringExtractor in 2025 and saw the same result. It seems to work selecting values from the start like Start 4 End 7, or Start 2 End -1. But having the start be negative seems to always return no value. The change listed for the V2-V3 upgrade was adding bulk mode support.Hoping I am just missing something/doing something wrong here.

Hi all. I am just trying to do something very basic but keep getting a “1019 error. The specified feature could not be updated or does not exist” when using the update feature writer.This only happens with polygons and lines/polylines but works fine with points.The workbench below is taking a polygon boundary dataset from portal, taking a polygon from AGOL putting it through a change detector - whose unique identifier is a name in both features- then updating/inserting/deleting when necessary to essentially make the AGOL layer the same as the portal layer….Or in theory this is what i want it to do. Any help would be much appreciated.  

When ‘Remove Output Attribute’ is selected for ‘If Input Attribute is Missing’  The missing attributes (the attributes with no data) are still present in the output.  Any clues? 

I’m currently dynamically reading web feature service layers by using a feature reader and trying to write them up to AGOL. I have no issues dynamically writing to a File GDB, but if I attempt to write to AGOL, I only get a Python KeyError, which isn’t telling me anything. Message Type: fme::internal::_v0::py::ExceptionPython Exception <KeyError>: 'Cadastre_Address_LGATE002'ARCGISONLINEFEATURES writer: An error has occurred. Check the logfile above for detailsThis only occurs when I want to write dynamically to AGOL, if I just write the exposed attributes it functions. Is there any way around this? I’m aiming to use one workspace to read in the features based on parameters, and write it out using parameters, as a way of creating and updating feature services.I should note that it seems to be half creating the feature service itself, but when it comes to write any features to the newly made feature service, the error appears.Thanks

Anyone ever developed a VS Code “language” for FME logs files? Years ago somone -  I wish I could remember who _ did this for NotePad++ and it was awesome.The defaul VS Code log view is actually not bad so this is really a - “would be nice”

Is there a way to specify that the email needs is high priority ?

Hi there, I got a weird error when I attempted to use featurewriter transformer to write feature into SDE dynamically (see the error screenshot below). Could someone please explain what is the error is talking about? Is there any solution?Thanks in advance for your answerAlan

I am trying to use a template file in an excel writer for my data. The data is collected from a number of sites, so I was aiming to use the site id attribute as the sheet name to export a new sheet per site. Unfortunately the template is only being used for the first site which passes through my writer, and the other sheets are unformatted. Has anyone encountered this and found a solution to apply the template to all sheets if multiple are being written in the same feature writer? 

I’m using an FME FeatureReader to read a content of an Excel file containing various values, including decimal numbers, some of them small with more then 5 decimal zeroes.The FME, apparently, handles these small numbers using scientific e notation.After processing the data, I write it into a CSV file using a FeatureWriter. The problem is, that the small numbers are written in their scientific notation form, and not as real decimal numbers. This is causing an issue further down the line.I tried various things to force the FME to write the numbers as decimals:forcing datatype of the affected attributes in the FeatureWriter to Decimal or Real using AttributeManager to change the datatype of the affected attributes to Real, Decimal and even String forcing the datatype of the affected attributes in the FeatureWriter to String changing the datatype of the affected cells in the Excel file to TextNothing helped.

Hello! I’m trying to figure out the best way to aggregate values by the most common words. I’ve found a few threads and documents but not quite what I was looking for.For example, I have a list of building names and numbers where each entry can have a of variation of a building name and number: “1000 The Coolest Building Ever”“1000 Coolest Building”“Coolest Building”“100 Coolest Building Dr.” I would like the output to be “Coolest Building”, as it has common base words across all features. Is this possible? Bonus point if a variation of “Bldg.” “Bldg” can be included. Any advice/guidance is appreciated! 

Hi FME enthusiast,               I am trying to read a large size of shape file using fme form (formerly desktop) where the file size 2GB. when I select the file in the esri shape file reader and try to add in workspace I am get the error like image attached below.The server have enough space to perform but I am receive error attached. Did anyone have face this issue earlier?. If anyone have any suggestions, all would welcome. Thanks in advance.!Notes: These shape files are exported from Smallworld using FME only.  I am using FME Desktop 2020.1.1.1 32 bit version.   

Hello,unfortunately I do not know how to solve the following problem. I have many points and lines and would like to create a connection to the line layer for the points. The lines should not be drawn directly to the starting lines as in the second case, but an iteration should take place. Here is the process as I would describe it:1. a point is taken and the closest point to the line layer is determined and this line is also created2. the new line is added to the existing line layer3. the next point is taken and the closest point to the line layer is determined. The new line layer may result in a shorter route than the original layer.4. the new line is added back to the original data set, etc.So far I have tried various workflows with a loop, but unfortunately I have not gotten very far. 

 How to apply geoid when converting ifc to cesium 3d tilesHello, I am converting ifc to cesium 3d tiles. The photos below are the photos that were converted. If I do not apply geoid, the conversion is done well, but if I apply geoid, the following error occurs. In the Vertical option, Geoid Height Grid, .gdc, .gtx, etc., the same error occurs no matter what file I put in. Is there any solution? The operating system is mac, and the corresponding fme version is 2023.2.  

Likely known by many here, however, I can’t see it documented officially so I’m going to spell it out.If you have created a CustomTranformer or are working with one you need to be very careful how you use/reference parameters.There are many gotchas when working with CustomTransformers but this is the one that trips me up the most. If you define a parameter in a Custom Transform with an attribute value this will not always be treated as a Global Parameter inside the transformer. I.e., depending on what happens in the Transformer the value will not always be accessible.I saw a great comment by ​@ctredinnick in this thread from a couple of years ago: where they mention that Parameter Values defined by an attribute value will be treated in a similar way to unexposed attr

I would like to publish the app so that the end user can optionally select a variety of filters including:date ranges static attribute fields (A or T) dynamic input fields (for example if a new business code is added to the source data)I have been able to publish the user parameters in the app but the data does not filter from the results set.  

I built a dynamic workflow to change a attribute for CSV file. It turns out that the attribute name is changed but without value in the output CSV file. Please could you help solve the issue?The input CSV file and workbench has been attached with the post.

Hi All,I'm still somewhat new to FME and am hoping someone can advise me.Through another workbench I have been able to gather a a list of service URLs from an AGOL. I would now like to automate the process of creating a new item in ArcGIS Portal via the New Item > URL workflow.I have looked through the Esri ArcGIS Portal Feature Service Reader/Writer and a few other transformers but none seem to accommodate for creating a referenced item via URL. Google is leading me nowhere either.Any advice or pointers?Thanks very much for your time!
