BAPI_ACC_DOCUMENT_POST

Hi Guys

I am trying to use BAPI_ACC_DOCUMENT_POST for Asset posting in G/L Account.I need to use the because I want to check the import Data with BAPI_ACC_DOCUMENT_CHECK, coming in via Excel File.

I use the Bapi, but how should i fill the structures/ tables - any code lines ? See my example and my return table ...

===> But the WBS ELEMENT exist. Also strange, if I run the bapi again in the se37 the error " WBS element does not exist" is gone.
