I am completly new to IS-U. We are using the DataSource 0UC_SALES_STATS_01 in SAP BW and had to migrate this DataSource to version 7.x. This was successful. Initialization was successful as well. I can get data using Full-extraction.
However, a delta-extraction doesn't retrieve data (process remains in "yellow" status and says that a response from source system is missing).
Another problem is, that a certain billing class is not being delivered.
As I am not familiar with IS-U: where can I have a look at this delta-problem and at the missing billing class?
