I created a production order, released it, and then made changes to the BOM. I went back into the production order and did Functions > Read PP master data. The system gives the message "error when checking BOM - reading routing without BOM not possible after release".
I have deleted all relevant (1) inspection lots (2) transfer reqs. No transfer orders exist and no material movements appear to have been executed.
What am I missing? Why won't the system read the BOM?
