Troubleshooting
Problem
In the exported LP file, the OPL Model decision variable and constraint names are not displayed. CPLEX auto generated internal names are displayed.
Resolving The Problem
In OPL a default limit of 100 is set on how many entries an array (or map in Concert terms) or constraint must have to be considered as big for display and naming purposes. If the limit goes beyond 100, the names will default to auto generated variable names and constraints.
The Big map naming threshold parameter can be increased if this limit is met.
Ex: settings.bigmapthreshold = 100000;
