Hi all,
I try to implement the following index domain in a constraint but I get the error “,)” is expected.
OperationsPOforJ(i) and OperationsPOforK(i) are two subsets of set OperationPOs. Am i making a typo or is it not possible to use two “in” functions in an index domain?

You would need to formulate this slightly different:
(i,j,k) | j in OperationsPOForJ(i) and k in operationsPOForK(i) and ord(j) < ord(k)
So on the left side of the | operator you only have the index names and on the right hand side you do all the restrictions.
