Asset posting BAPI_ACC_DOCUMENT_POST

Hi all,

We are using BAPI_ACC_DOCUMENT_POST for vendor and G.l line items, we want to add asset line with the same BAPI.

But we are getting error, by giving asset number in line item, program thinks it is a G.l account, so it returns with error like this G.l account does not defined in chart of accounts.

Where are we possibly making wrong in program,please suggest

This is urgent, hope you will help to find the right solution
