Hi Florian,
Could you please clarify the below points
Why are you using ADDD as delta process or FI totals table related data soruces?
Whats the delta pointer that you are using?
Whats the safety interval set for this data source?
In your case try to change the delta process from ADDD and AIED( After-images with Deletion Flag via Extractor) will solve you issue. Try this option and update me the status.
Set the delta pointer as TIMESTMP and safety interval as 3600 secs( depends on your buiness need)
Note: ALL the FI data sources works on TIME STAMP Mechanism. and Delta process used is AIE or AIED.
Regards
KP
