Backorder Processing

Hi,

Please help me to resolve back order processing problem in sales order.

Last year, a sales order was created on 09.05.2006 for a material with 9 order quantity. Two schedule lines were created, one on 10.05.2006 (with quantity 5) and another one on 17.05.2006 (quantity 4). Somehow user has created delivery document for all 9 delivery quantity on 12.05.2006 thus post goods issue was completed on the day itself. Sales flow is completed with invoice creation.

Now when we run MD04 transaction, material quantity 4 is committed against the sales order. Transacton V_RA also displays committed quantity against the sales order. Actually all 9 quantities were delivered on 12.05.2006. But second schedule line quantity 4 is still blocked for the sales order. Could anyone of you explain the procedure to release the quantity commited against sales order?

Regards,

A.Prabhaharan.
