stock determnation for sales order stock

Hi all,

for our SAP retail solution - we have requirements for moving Consignment stock to Sales order stock for home delivery . Then Sales order stock needs to be withdrawn for inter company 643 movement . The stock determination is maintained as K first & then F with relevent settings in SPRO & article master, for consignment article -when sales order stock exist & delivery is created for intercompany PO with sales order on account assignment to transfer stock from Store to DC, SAP error message is not allowing to post Goods issue.

What settings do we need to maintain for this to happen to withdraw from Sales order stock for consignment article ? Any help or information is highly appreciable.

Thanks
