Error in MRP Runs

[SAPSupport]

Hi,

We get error in our daily application job - MRP run over all MRP materials.

It does not work with both applications - "Application jobs" and "Schedule MRP runs".
This error causes wrong requirement dates for needed materials and prevents the lead time scheduling in Planned Orders.

How can I avoid this error?
Thank you!

The best way to avoid the number range from being exhausted is to use 'Planning Mode 1' as often as the business process requires. It is not possible to re-use the numbers again once they have been used and deleted by 'Planning Mode 3'.

See further information in this KBA:
3154180 - Planning mode 3 should not be run regularly, only in exceptional cases

The short term solution to make your MRP work is to extend the number range. The related Configuration Step IDs are listed below for your reference:
