I created a Data Transform and Mapped to DLO, When I run Data Transform, It's taking too much time to active, that time Data Transform Status as "Processing", after a long time it's showing the Data Transform Status as "Error". I did not got any email and log also to check the issue. Can anyone help me to resolve the issue, the only i can move further. Please find the attachment of the image as well @* Data Cloud for Marketing (fka CDP) *
This usually happens when the data transform is configured either to process too much data, or if there is some issue with any of the data streams/DLOs/DMOs used. You can check the following:
1. All the participating DLOs, DMOs etc are active and working (not in error state)
2. Check if there are any unsupported functions, incorrect field references, or source DLO/DMO fields that may have been renamed or deleted.
Also, is it possible to share the screenshot of the Data Transform itself (its components) to check if there are any joins or transformations making it complex.
