We have a customer where stock is consumed by a variety of processes including SO creation, master planning etc and some time stock allocation does not work as expected. This could be stock not being marked/reserved, the wrong batch being used, work orders not reserving… These are raised after the event once key variables (ie the state of stock batches etc) have changed and we do not have replication steps.
My question is how can something this complicated be best investigated if it cannot be replicated using precise steps to generate the expected error?
Even if we take a copy of live that has the errors and refresh into UAT this is not ideal as the system has ‘moved on’
I am thinking about principles rather than a concrete solution. Does anyone have any ideas?
