You can use this Customizing activity to control how you want the confirmation of production orders from a manufacturing execution system (MES) to be processed by the ERP system. You can specify whether the confirmation is to be executed directly or whether it is to be written to a queue for asynchronous processing (inbound queue via qRFC).

You have set up integration between the ERP and the MES and are distributing production orders to the MES.

If you do not make any settings here, the confirmation of production orders is always processed immediately via the modules BAPI_PRODORDCONF_CREATE_TT and CO_MES_PRODORDCONF_CREATE_TT.

Maintain this activity if you expect a large volume of confirmations from the MES and you want to relieve the pressure on the confirmation interface to the ERP system. For each production plant, you can specifiy how you want the confirmation from the MES to be processed.

If you choose confirmation via the inbound queue, additional configuration steps are required:

• Make sure that the inbound queue is registered for processing. To do so, call the transaction SMQR and register the queue MES* using the relevant pushbutton. The remaining parameters proposed by the system can, as a rule, be used.

• Register a display program for the inbound queue using transaction SMQE. In transaction SMQE, choose the function Edit -> Register Display Program and enter the display program CO_MES_INT_QUEUE_DISPLAY_TOOLS here for the queue name MES*.

• If you want the system to restart the inbound queue independently when lock errors occur, you need to configure the error message CO_MES_INT100 so that it is issued as an error. To do so, execute the activity Specify Characteristics for System Messages.

The system now writes the received confirmations into an inbound queue with the name MESINPPORD so that a separate queue is created for each order and the call time for the confirmation module is shortened to the time required for registering the queue. The inbound queues are processed asynchronously by the ERP. You can use transaction SMQ2 to monitor the inbound queue.

SAP recommends that when you are using the inbound queue that you decouple the goods movements from the confirmation. Otherwise, lock problems might occur when the components are being posted due to parallel processing of the inbound queues. You can make the relevant settings for process control in the Define Confirmation Parameters activity.
