Running Identifier job with KB modified by KBCUSTOM to remove product.
Job abends with U101. (user abend)
Identifier Job abended BECAUSE it failed to find the product definition for a module (ADSIMX01). The product is XPEDITER/TSO and it seems it was deleted with a DELPROD XPEDT-91 using job(KBCUSTOM)
Resolving the problem
L3 recommendation is to not use TLCMz Software Catalog Customization (KBCUSTOM) Tool. Using the Software Catalog tool to remove data from Software Catalog is very likely the cause of the abend in the Identifier.
