When running job AL2DCA70 do you run it for ALL the PLANs or run it only for the PLAN that has been updated by a PTF.
Release : 12.1
For example PTF LU05220 only updated plan SASSDT62.
You could just import that plan, but please note it's not a problem to import them all again. The HOLD data recommends running AL2DCA70 as is without modification (All the PLANs). Make sure you always use the most current version of AL2DCA70 from the CAL2JCL dataset because of the PTFs updating it.
If you want to load the one plan only, please don't modify the original AL2DCA70. Make a copy and modify the copy.
