Previous revision

Question

We need a report to show the quantities for the current Purchase Order (PO), and the quantities for the previous revision. This way we can see at a glance how the quantities have changed.

which should hopefully make things a bit clearer. What I need to end up with is the data in the red rectangle. This shows the data for the current revision (3) of the PO, but it also shows the quantities for each of these items from the previous PO revision (2).
I can't see how I can get WEBi to look at data from the previous revision. I can hard code it to look at revision 2, but I need this to be dynamic as the current PO revision could be anything

Answer 1

the best way to perform you issue is to create a view or alias from the PO table in the unviserse and put it in some context in the universe
so when you inquiry the PO from the Webi it can give you automatically the Previous PO with the same item in the Current one and also you can calculate the variance and the growth of the Itmes between the 2 POs
talk to your IT Departement about this issue and discuss it with them.
if you want to make it in Webi, you can handle it too, but it will be more compliacted and it will take much of time.
you can use the multiple queries concept with some restrictions and subqueries.
i wish you the best and i wish you success with ur IT to let it be done at the universe level.
good luck
