Connect a Word document instance to Generic Object Services/BDS

Hello all,

how can I manage to get a word document created via the Doc_template step to a certain Business Object (like Business Partner). I tried to trace that but I got lost in generations of codes like archivelink, sap office, knowledge provider etc.) I guess it should not be that difficult as I have the key of the word doc instance and the key of the business partner instance. What I want at last is to have that word document linked via attachments/linked objects or something similar....

Kindest regards from Germany,

Markus
