Import Error - HANA based BW Transformation on BW 7.5 (-- SOLVED --)

Hello community,

we refactored an ABAP transformation to a HANA based transformation. In detail, we refactored a simple field routine coding from ABAP to SQLScript. With several other transformations we did this before in the same system - successfully.

Now we are facing an error when trying to import the HANA based BW transformation. The import from dev to integration system failed with RC12.

Job log SM37:

The generated AMDP class is in the system. We can find the class in SE80/SE24. So, we have no clue what is the issue.

We know, that there a some limitations for HANA based transformations. Our field routine coding did not delete, sort or extend the data set. The target is an ODSO and source is an IOBJ.

What we tried:

- delete the transformation and build a new one

- re-generated the AMDP routine with program RSDG_TRFN_ACTIVATE in integration system

Does anyone has any idea?
