Qty not getting Confirned in Sales Ord created through IDOC: ORDERS05

Dear Experts,

I am new to IDOCS.

I have an issue where Quantity is not getting Confirmed while created Sales Order via IDOC : ORDERS05. I checked the Segemnt E1EDP01->E1EDP20 for the Scheduled Line Items. Here the only DATE field EDATU was getting populated.

So while debugging I also populated the field WMENG into the segment E1EDP20. Still the Confirmed Quantity was not getting Updated in VA02/VA03.

We we created the sales order manually the Confirmed Quantity was getting Updated. Hence no issue.

Kindly Guide..

Regards

Gopa
