Stly,

First i want to know what changes are u doing for that data item
1) Renaming
2) Changing the length
3) adding new variable
4) Deleting a variable

Make a fairscan to identify how many pgm are using that particular copybook

1) U have to change the name of the variable whenever it is used in the Pgm
2)If the pgm are moving value of that variable to some other variable then we need to change the length of the coorosponding variable also
3) we have to add functionality for that new variable if req
4) we have to delete each & every occurance of that variable from the pgm

Hope it will helpful

Stly,

If you are increasing the occurs limit for a field then if business requires then u have to add funcionality to pgm to populate those fields
