Access Seq - Exclusive indicator - How does it work

Hi ,

For one of the Access seq in pricing we maintin 2 tables. Acc to the buss process ,

IF I TICK THE EXCLUSIVE INDICATOR - What does it do?

I know that If i maintain record in 1st key combination system will read the record and it won't go to the search the next key combination.

If i don't maintain the record in 1st combination will it go the 2nd key comb record? or it will stop without even searching in 2nd key combination?

Pls suggest.

Thanks

Mahe
