ME083 - Enter Free of Charge in PO - ME21N

Hi Gurus,

When ever i am creating PO using ME21N, in few cases system giving error message as " Enter Free Of Charge" and as expected invoice receipt indicator in item detail is removed automatically.

Even if i untick, free of charge indicator & tick inv receipt indicator again, system is still not allowing me to save the document.

Kindl let me now, why Free of charge indicator is coming automatically ? How can i avoid this error.

Surprisingly System message ME083, is not maintained at all in our system.

Best Regards
