There are some posts touching this issue, but with no clear solution or referring different issues, actually. So my problem is as follows:
There is a Data Source based on Function Module. One of the fields gets populated correctly when running in RSA3, but it is not populated in PSA, when loading data using regular Info Package with no selections. Interesting: When using selections in Info Package, the value of the field appears in PSA populated correctly. Data Source has been replicated and activated many times. There are no dumps and no errors. There is no difference if the Info Package is full or delta initialization mode.
Every hint is appreciated.
Thank you in advance.
