i want to create an activity with reference to the order. Like you can do it in WebUI. To create an activity i actually use the Bapi BAPI_ACTIVITYCRM_CREATEMULTI. To test the Bapi i use the CRM_CALL_ACTIVITY_INTERFACE Programm.
Now if i enter the object id (guid) and bor object type of the related order header in the object link section it doesnt work. I get a short dump which says that i want to create an item relation without a header realation.
So has anybody some ideas for me?
