Negative Posting Using BAPI_ACC_DOCUMENT_POST
i hope you can help me here with a development i have to make.
in theory what i have to make is the following:
I have a FI document saved in the database, and i have to read that document and post a new one which is the negative one of it. And then i have to make the clear of those 2 documents.
What i've thought of doing is reading the document using FM "BBP_FI_DOCUMENT_READ" and it gives me several tables with the data of the document. Next i'll try to use the BAPI "BAPI_ACC_DOCUMENT_POST", b ut my doubt is how do i do the negative posting with this BAPI ?
