1. If foreign key relationship is defined for this primary key field, you will have change the relationship. Check the foreignkey relationship is this second table, by clicking the 'check' button.

2. All function modules, includes (also TOP include) will be loaded into memory.

hi ,

1. you cannot able to delete the primary key that is having a forien key relation ship. It will show an error primary key change cannot be permitted.

2. The entire function group is loaded in a program the first time that you call a function module that belongs to it.

The system also triggers the LOAD-OF-PROGRAM event for the function group.

The function group remains active in the background until the end of the calling program. It is therefore a suitable means of retaining data objects for the entire duration of a program. All of the function modules in a group can access the group's global data.
