I want to create some documents and link these documents in material master additional data. I want to use FM 'BAPI_DOCUMENT_CREATE'. When i went thru the functional documentation i found that there is a table BAPI_DOC_DRAD. Here in documentation table and name and object key is passed. What is the purpose of this table. I want to know is there any way that i can add this document to the material master using the same BAPI.
