0FI_AP_4 delta issue

Hi guys,

I'm using the DataSource 0FI_AP_4 to load FI line items (with delta) from a ECC6.0 system. I created two InfoPackages (one for the first delta init and one for the delta load). The delta init worked fine and loaded the FI items into my PSA. After that I executed a DTP to my DSO and activated the request.

Now I posted an new FI document and executed the delta load - but the process monitor says there is no data. The delta queue (RSA7 on ECC) is empty, too.
Do I have to perform some additional steps to get the delta data?

Thanks in advance!

regards

Václav
