Not in clause

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,

CROSS, DIFF, ELSE, IN, INTER, NOT, OR, SYMDIFF, TO, UNION, WITHIN, [, ], ^, ^=, |, ||, ~, ~=.

ERROR 76-322: Syntax error, statement will be ignored.

Correct syntax is:

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] <= BigM * IsLSPDC[c,d];
