    Hello,

    I just installed OPL 12.2 on my computer. I have a model that I created with OPL 6.3. I imported this model into OPL 12.2 and it told me the model has an error. It said the decision variable (or expression) "Transittime2" not allowed. Lucky me I still have OPL 6.3 installed and I can confirmed that it runs fine in OPL 6.3.

    Any help is appreciated.

    thanks,
    Boon

    I decided to contact IBM support and found the solution. The problem was that OPL 12.2 does not effectively recognize expression in the constraint. the solution is to put parentheses like this --> transmitted time=(........................).
