From SAP library...
-The quality level is, as a rule, only updated on the basis of the dynamic modification valuation after the usage decision has been made for an inspection lot (Dynamic Modification with the Usage Decision). However, you can also update the quality level at lot creation (Dynamic Modification at Lot Creation). In this case, acceptance decisions are made for an outstanding inspection lot.
-Dynamic modification at lot creation is useful, if several new inspection lots can be created, before you have completed the inspection of the first inspection lot.
-During lot creation, the SAP system reads the current inspection stage(s) for the quality level and uses this for sample determination.
