I have created a rework order and i want to peg a sales order to it. The sales order field in the rework order is greyed out. My requirement is to print labels for a sub contracting item and sub contracting is a purchasing sub contracting. I can not create a normal production order for externally procured item, so i have created a rework order without any materials in the order. Can you please tell me how to peg the sales order to the rework order.
