If your MRP is not working how would you troubleshoot it? It is very simple than you think. Check each source of demand and sources of supply. Check whether there is anything wrong. If you are running AFS in MTO (Made To Order) model, then this means, checking your SO for any problems, Checking your BOM for any issues, checking for the planning horizons and checking for planned orders and so on. But if you have checked all these but you can find nothing, when it seems like you have checked every possible options, you have one more check to be done. This check is really important if the MRP is not running for any of your SO (or other sources of demands) or for any of your materials. The check is the number range check.

Yes, one of the MRP issues, I found few times in my consulting carrier happens due to the exhaustion of numbers allocated. For an example, if you run out of numbers in allocated planed order number series, MRP will not be able to create a planned order. Same logic applies for the Purchase requisitions too. Check this and if the numbers are exhausted or nearing the upper limit of the allocated number series, you have to extend your number series or allocate a new number series for the document type in question.You can check these settings using transaction OMI2.

I though this quick tip might help you.

We upgraded one of our instances from AFS version 3.0b to 6.0 some time back. We had few issues with migrating categories. But after migrating, we never had a need to create a new category in 6.0 environment. But when we had to we faced few issues.

To configure a category you have to first create a “Characteristic”. Then in SPRO, you have to create a category structure and then create a coverage strategy and assign the coverage strategy to the category structure. Configuration node can be found following the path SPRO -> Logistics – General – >AFS Categories.

We followed the process but the results did not work as we intended. With the help of AFS support team, we found Relevance and Conversion buttons were missing on the CT04 screen and as a result configuration could not be completed properly. So they recommended the SAP NOTE 1041015 and it solved the issue for us. It put the buttons on the CT04 screen and enabled us to complete the configuration.

Caution: Please read through SAP documentation before implementing notes. If required seek the SAP support. These steps might not work, or even might do harm in your case.
