facing issues while pegging

[Former Member]

Dear All,

I m running a demo on Project Manufacturing for Aerospace & Defense Industry and facing some issues while doing Pegging.

The demo involves 13 processes starting from creating a sales order with WBS element assignment, grouping them into two groups then doing MRP run in APO and converting planned order in APO into Production order, then doing procurement execution which involves procurment of externally produced material, then doing manufacturing execution which includes in-hose production and then a final assembly for creation of the end product which is a missile and then an outbound delivery and later I need to do pegging and distribution and settlement of costs.

I could complete all the steps and the end product was delivered but while doing pegging I'm getting error messages.The error suggests that two of the production orders are not pegged properly. I do not understand the reason for this error and can not identify what is causing such error.

The error message is "Replenishment Object OR**** Cannot be assigned".

Please help

Warm Regards

What version of SCM are you using?

Which PPDS heuristic are you using for the MRP run?

What are the product-location settings for pegging?

Try to re-run the process and run /sapapo/om17 between each step and you may find that some of the max pegging arcs are being corrupted between LC and DB due to a mix of soft/hard constraints and limitations with pegging. <--- In the world of 3.1 to 4.1 we found this to be true, but in 5.1 it is fine.
