Dependent requirements with external processing operations

292 Views

Hello,

I'm facing a problem regarding dependent requirements from planned order for materials that are shipped to subcontractor for external processing operations.

My settings are the following:

I have created a finished product routing, one operation is processed externally, while the last is internally processed. During the routing creation I have assigned to the external operation components that should be sent to the supplyer. Assumption: I have already sent some components stock to the subcontractor that must be used to complete the external phase.

Scenario: we have an indipendent requirement on the finished product, during the MRP run, the bom is exploded and will be generated dependent requirements on bottom levels, but the MRP doesn't consider the subcontractor stock and if a shortage exists it will create a purchase requisition for components that must be supplyed. This happens only until we convert the planned order of finished product into production order. After production order creation, subcontracting purchase requisition will be created and the new mrp run will consider the subcontractor stock, if a purchase requisition had been created before the MRP will delete it.

Thanks

Best regards.
