Posting this question in a new thread.
I have a constraint below that gives syntax error.
con DC_LSP_Direct_Link1{p in Ports, t in Transit,c in lsp, d in DC: d not in {'SAV','LAX'}}:
ContainersfromPortstoLSPtoDC[p,t,c,d in DC: d not in {'SAV','LAX'}] <= BigM * IsLSPDC[c,d in DC: d not in {'SAV','LAX'}];
This is the error
ERROR 22-322: Syntax error, expecting one of the following: !, !!, &, (, *, **, +, ',', -, .., /, <, <=, <>, =, >, ><, >=, AND, BY,
