Changes in Customizing of PIRs don´t update tables PBIM-PBER.
CUSTOMIZING OF PIR NOT UPDATED IN TABLES PBIM/PBER:
This blog deals with this topic that generates confusion and an unexpected behavior
in the consumption and reduction of PIRs.
If you change the requirement class of a requirement type it is
necessary to reorganize (delete) all effected PIRs from the data base.
The system copies the requirement characteristics from the customizing
to the data base tables for PIR (e.g. PBID, PBIM). These requirements
characteristics in the PIR tables are not adjusted automatically by
changes in the underlying customizing.
Please note that the header entries for PIR (PBID, PBIM) still persist on the data
base if all PIR items (single PBED entries) have been deleted.
To consider the current customizing settings it would be necessary
to reorganize appropriate PIR header first. This can be done by
using the transactions MD74, MD75, MD76 (usually it is necessary to
run all transactions for appropriate requirements).
