Hi Sundeep,
The PGID should always be 1 one when it comes to the B1 Price, but it will have multiple PGID's in the table.
What I want to create is if the PGID is not one, then replace that PGID B1 Price with the one that is for PGID 1 at the time of transaction.
If that makes sense. The B1 price will change through time and what I want to do is compare Sell price for any PGID against the B1 Price for PGID 1 and see what the difference is.
