Inter Co. Stock Transfer

Dear Team,

I am facing Some Issues while making Inter company invoice. The situation is
Mr. A is the owner of Two companies B & C, he deals in serialized items Now he want to transfer his Stock from Co. B to C using internal customer option.

By following all the steps of Internal Company invoice he makes the sales invoice against company C Here two situation arise.

  1. when Update stock is checked it allowed to submit the invoice but when moving to Create-internal company invoice it gives message "warehouse of co. B does not belongs to co. C

2.when Update stock is unchecked it allows to create the purchase invoice but it does not bring the serial number automatically in purchase invoice which is already there in sales invoice & secondly after entering the Serial number manually and submit it gives message “Serial No 123456789 has already been received.”

Please Help to solve this issue
