FB01 - Create an outgoing payment with a Bapi

Hi there, I'm trying to simulate outgoing payments with BAPI_ACC_GL_POSTING_POST but I'm finding problems, does someone knows if this is the right bapi ??

I'm finding problems 'cause the bapi needs a gl account but I have to put the vendor code and I don't know if I'm doing right, I'm putting the code for the items (25 and 50) in the accountgl-doc_type field.
