Problem while Error Handling thru BAPI_PO_CREATE1

Hi,

currently im facing problem while generating error thru BAPI_PO_CREATE1

im calling bapi two times thru loop iteration,

as my data is faulty , so for 1st iteration im getting 3 error in it_return structure.

now in 2nd iteration im getting (3+3)

repeted error which is geenarated earlier(old 3 err) +(new 3 err).

im refreshing all internal table,work areas and variables, still im getting same problem,

please provide ur kind suggestion on this.

refresh : <all it>
clear  : <all wa>

Loop at it into wa.

refresh : it_return.

CALL FUNCTION 'BAPI_PO_CREATE1'

Tables = IT_RETURN

endloop.

Regards
