We create sales orders (Internal number range).
When the below stock is receipted, SAP will release orders by order number A To Z. This is done using VL10A as a background job.
If we only received 1 unit on delivery, sales order CES24720 will be allocated 1 unit when in ideal world, should go to sales order EBY05241, ordered on 05.06.2014.
System requirement is to allocate by date (old to new) to ensure with reduced inventory holdings, an order who has been waiting for the longest, gets the stock first.
Hopefully, someone can help!
