No Extraction of Data per InfoPackage in DataSource based on a generic function module

Hi experts,

I have create a generic function module to extrct data from different tables to the DataSource.

The function module in r/3 works fine and the test looks like good (SE37):

1 Entry as Result of the function module (it´s correct)

The Exctractor checker for my generic DataSource (with the generic function module as source) in r/3 works also correct (RSA3):

1 Entry as Result of the generic DataSource (it´s correct)

Now my big problem is that I cannot extract the Data by execute the InfoPackage in the BW:

The status of the PSA-Request is "yellow" (not yet finished) a very very long time and the status is not changed to "green" (Status OK).

Any ideas what kind of checks I should do?

Many thanks in advance!

Best regards,

Michael
