What does the 'Num-All' value represent in a BPCA analysis result, and how should you interpret a low Num-All hitting only a table like NRIV?

Num-All = the number of objects in the intersection of the TBOM and the transport/change object list. A low Num-All that only touches objects like the NRIV number-range table is likely benign and may not require full regression testing of the affected transactions.
