how to get complete list of docs in CDESKs SAP view ?

Hello developers,

this time I plan to add new functions to CAD desktop. I'm using BAdI technologie.

While using method IF_EX_CDESK_TBM_ADDIN~PROCESS_NEW_FUNCTIONS

I want to get a list of all plm docs of the SAP view.

Parameter 'documents' contains only the selected docs.

Parameter 'documents_add' is always empty (why ?)

With function CDESK_GET_SELECTED_DOCUMENTS I get only selected docs, too - but I need all docs - particularly the header document.

Where can I get this information ?

By the way: in IF_EX_CDESK_BADI_MAIN~ON_FUNCTION there are two parameters. 'documents' and 'documents2'. What is the difference ?

Thank You for helping me ...

Greetings from germany.
