Working with the product customization:
TSO EX HLQ.MAT.CEESCLS0(TRCUST)
Got an error message:
DATA SET HLQ.MAT.CEESCLS0.CLIST NOT IN CATALOG OR CATALOG CAN NOT BE ACCESSED
Why is the CLIST TRCUST attempted to find that dataset?
The TSO EXECUTE command was incomplete; the required parameter PREFIX(&hlq) was missing.
Note that the full command is EX '&hlq.CEESCLS0(TRCUST)' 'PREFIX(&hlq)'
