Error message in BAPI_INCOMINGINVOICE_CREATE1

[kirankumark2]

Hi,

I have developed a program to create vendor invoice using BAPI_INCOMINGINVOICE_CREATE1, invoices are getting created but for some cases system throws a strange message "this billing document still includes messages" when I use BAPI_INCOMINGINVOICE_CREATE1 whereas when I use BAPI_INCOMINGINVOICE_SAVE invoice is getting created with Defined for background status. I have called BAPIS like below if First BAPI failed i am calling second BAPI with same data.

Note: This program executes in Background. This BAPI is called inside a LOOP statement. When we execute the same program in Foreground this message is not throwing and invoice is getting created with same data.

Some body help me to sort out as we are unable to Find the Root cause
