Table values not getting transported to BAPI

Hi,

I am trying to use the BAPI BAPI_DELIVERY_GETLIST, i need to pass Delivery Information on table IT_VBELN. I imported the model in VC and have flipped the port on IT_VBELN to make it an input port.

The issue that we are facing is that table values that we add into the IT_VBELN do not get transported to the BAPI call.

Has anyone else faced a similar issue? Looking forward to your inputs.

Thanks,
