First of all, you have to make shure, that in the new X(7) field only numeric data could be entered. Otherwise the receiving to fields with COMP-3 are not correctly packed data. Result will be S0C7.
I think, first off all, you have to figure out the reason, why the field was changed and then have a logical look at the depending programms, which
are working with that field. There can be unpredictiable results.
1.) X(7) fits into S9(7) COMP-3.
2.) Which filler. Is the receiving field smaller, then result is truncation.
3.) Have a look at the data-structure of both records.
4.) The content has to satisfy a level-88 so that this is set tu true.
This business requiremnt-Field needs to be changed from S9(7) COMP-3 to
X(7). For this iam identifying various secenarios how the field was used in the programs like in Individual MOVE's, Group MOVE's, Logical Expressions etc.
I found some cases , I could not able find the solutions for above cases
