BAPI_ACC_DOCUMENT_POST

Hi All,

I am using BAPI "BAPI_ACC_DOCUMENT_POST" in one of my programs to post the documents. I am able to post the documents successfully if I am trying to update less than 12 items. But not able to post if more than 11 items are there. I am getting this error "FI/CO interface: Line item entered several times". Please suggest if you have any solution for this.

Thanks

Smitha
