CVAPI_DOC_CREATE - no Workflow Event DRAW-CREATED in SWEL

Hello.

i am using fm CVAPI_DOC_CREATE to create a DIS.

DIS is created successfully but there is no event CREATED for BO DRAW triggered and shown in tx SWEL.

Do you have ideas why this event is not getting triggered ?

I am using SAP ECC 6.0 with EhP 7.

Thanks a lot for your ideas.

BR,

Sebastian
