SAP PI: RFC adapter not sending changing parameter values

395 Views

Hi,

I am currently working on a file to RFC scenario in PI. The data is sent to a function module that takes importing as well as changing parameters. However, the RFC adapter does not seem to send the values for the changing paramters.

When I debug the function module I can see that the values for the importing parameters are set whereas the changing parameters are empty. The mapping looks fine - SXMB_MONI lists all parameters and their values.

Even weirder: When I check "commit handling for single BAPI calls" then the changing parameters are set! However this leads me to another problem since the function module does not return a paramter with name RETURN.

Any ideas? This is what I tried already:

- Change RFC communication channel and activate it to refresh metadata.

- Clear cache.

Cheers

Michael
