WWII German ammunition data

One of the most interesting things about WWII German ammunition is the detailed markings on the boxes, even the headstamps. I understand why they went to this level of detail, but have always wondered if it really ever did any good. Seems to me that the quality control was pretty good and the testing and acceptance procedures would prevent “bad” lots of ammunition from ever being fielded. Do we know of any rejected lots, recalled lots, or other instances where the detailed information proved it’s worth? Period documents adressing this issue?

I once saw a US Army technical manual that listed lot numbers of ammunition from small arms to aerial rockets that were not to be used due to one defect or another. I recall much of this having to do with age and or storage. Maybe the German ammunition just was not around long enough to have benefitted from their detailed record system?
