Hi Vishal,
Sales Organization, Distribution Channel and Division are data that has a relation.
You need to get all the possible combinations to be checked,
for this you have the 'Organizational Unit: Sales Area(s)' standard table (TVTA).
Using these select options values, select TVTA table
and insert into internal table.
Loop in your internal table and apply your authority check (inside loop)
for these values (and combinations) available in your system.
And if necessary, it's possible to inform the detail to user, example
If the user doesn't have some combination you send
a message informing what combination
it's not available for his access.
