ERROR Domain violation for set

GAMS
1

In my model there is a variable x_i,j,k where i belong to J=J_1∪J_2∪J3.
for some constraints i is belonged to J and for other constraints i is belonged to J_1 , J2 ,…
for last case I am getting the error: Domain violation for set.
x_i,j,k is defined as binary variable.

Any help would be appreciated.

Hi

Without some code that reproduces the error, it is only for the clairvoyant to help you.
