Maybe someone can point us at the underlying problem.
We do infinite capacity on all our shop floor orders and have not had a problem in years. Out of the blue on one item planned orders generated the message in the title after March 6, 2020.
We looked at all the suggestions on resources and resource groups and turned off all of the capacity limits in workcenter parameters.
The error still occurred on this one workcenter/item. Not high quantity, no much labor.
Our workaround was to give it a different workcenter. Many other items use the old workcenter without a problem.
My guess is there a stuck bad record in a table that is confusing MRP.
Anyone have experience with this and a solution other than copying the workcenter and using the new one.
Debugging is about impossible due to the kernel code and recid to recid to recid on tables.
