Working on an OCPM data model and running into an issue where transformations based on SAP tables won't preview or publish anymore, regardless of which specific transformation it is, even standard Celonis ones fail as long as an SAP table is involved.

A few observations:

  • Transformations on other source systems (e.g. Dynamics AX) seem unaffected, so it looks specific to SAP tables somehow.
  • Saving with validation fails outright, saving without validation works, but publish still isn't possible afterward.
  • Existing, unchanged transformations still seem to run fine in the backend, so this feels isolated to the Objects & Events interface specifically.

Anyone run into something similar with SAP-table-based transformations?

Might be worth checking the data types on the SAP tables involved. There's a known issue where certain SAP-specific field types aren't supported by the Celonis SQL Engine, which can cause exactly this kind of preview/publish failure while backend jobs keep running fine. Trying a different, supported type on the affected column could help narrow it down.
