    Is this form not available?

    Just like：

         forall(i in A,<j,k>in Clients:j!=1,<i,k>in Clients,<i,j,k> in Totals)
           q[<j,k>]>=q[<i,k>]-d[i]-Z*(1-x[<i,j,k>]);

    Hi,

    you have an out of range.

    If you turn

    forall(i in A,<j,k>in Clients:j!=1,<i,k>in Clients,<i,j,k> in Totals)
           q[<j,k>]>=q[<i,k>]-d[i]-Z*(1-x[<i,j,k>]);

    into

    forall(i in A,<j,k>in Clients:j!=1,<i,k>in Clients,<i,j,k> in Totals:i in N)
           q[<j,k>]>=q[<i,k>]-d[i]-Z*(1-x[<i,j,k>]);

    then it will work fine

    regards
