Reproducing the Issue

  1. Go to Schedule MRP Runs App.
  2. Create a new job with: Recurrence Pattern = Repeat Job Every 1 Day(s) / Planning mode = 3 / Regenerative Planning.
  3. A warning message is displayed - Planning Mode 3 should not be run regularly, only in exceptional cases.
  4. The job fails with error: Recurring regenerative planning jobs with planning mode 3 cannot be run Message no. PPH_MRP248.


Standard System Behavior.


You're not allowed to schedule a recurring regenerative planning job with planning mode 3, because this way, the system would re-plan all selected materials and delete are recreate all planning proposals. This leads to a high CPU and memory load on the database, which negatively impacts the overall system performance. On top the number ranges for purchase requisitions and planned orders / dependent requirements will drain very fast. The system does not allow this.

Do not schedule recurring jobs with this parameter combination. You can always run/schedule regenerative planning jobs with mode 3 as a one-time job, as there might be good reasons to do this. There is no good reason to do this periodically, as the system automatically keeps track of what materials need to be planned. Also the system automatically decides correctly, if planning proposals cannot be re-used.
