I have the problem in stock against production order:
Our scenario is we don’t want to create a sales order. I create a production order that has 5 operations. The first operation is sub contracting. Through control key (External operation) I create the purchase requisition and convert purchase order in that operation. Through the PO I can issue the ROH and received HALB. When I received the HALB the stock of ROH is automatically reduced. But HALB stock doesn’t increase. In this case where is my HALB material for second operation?
In this case how to proceed?
Do you have a material code for HALB? if you have material code than you can have stock increased. I think there's some mistake with the process. the subcontracting in operation is only for the operation, not the material.
In your configuration, you subcontract the first operation of the FERT production. and there's no stock increase of FERT or HALB when the first operation is completed (confirmation by purchase order...)
And what you want could be possible like this:
You create the HALB material code, and you make it external procurement (F in standard) and with special procurement key subcontracting (30 in standard) (enter these fields in material master mrp2 view). Then you can create purchase order for the HALB material when needed, and send ROH material to the subcontractor for the purchase order and post goods receipt for HALB material and stock increases. And accordingly, since the production of HALB is a different process, not a sub process of FERT material, you should change the routing of FERT material to 4 operations, omitting the first operation, which is subcontracted production of HALB. And you should also change the BOM of the FERT material, and remove the ROH (which is used for producing HALB) and put the HALB material itself.
