Combination Of ProjId And ItemiD

For example :
Projid Item

1 1

2 2

3 3

1 2

1 3

2 3


1 1 (duplicates not allowed);

There should not be any duplication for Itemid and ProjId combination

There is no question nor description where your problem is, but maybe you need to create an index with those two fields and set the index property “AllowDuplicates” to “No”.

If it didn’t help, try to describe your question more clearly.


My thought also same way but demo data not Available
