Dynamic modification is more related to skip lotting than your acceptance criteria. Your acceptance criteria are based on the sampling procedure and sampling schemes you used. SAP provides a whole lot of standard, industry recognized procedures and related AQL values.
I have no idea what you mean by the following:
"When we had our first Batch we saw we can only write as a result of Quality inspections 0 or 1, and if we wrote 1, we got a Reject batch."
Was that a MIC result you entered? Was it the number of samples?
