SAP PI 7.3 WSDL delivery date not transfered

Hi everybody,

we have an E-Shop - PI - ECC landscape.

We post a SOAP request from the E-Shop via PI to ECC in order to get order information.

BAPI: BAPI_SALESORDER_SIMULATE

When testing the BAPI in SE37 it gives the delivery date (that is what we need) back.

Whet testing with the exact same data via PI or via SOAP UI, the delivery date is missing.

Any ideas?

Thanks a lot

Gerhard
