IBM ILOG CPLEX Optimization Studio v12.6 Fix Pack 1 and IBM ILOG CPLEX Enterprise Server v12.6 Fix Pack 1 available on Fix Central

APAR status

• Closed as fixed if next.

Error description

• Whe using decision variables in the ranges of all expressions,
  such as below
  
  dexpr  int  Exp1[ j  in  X, t  in  X] = count( all( x  in  0..
  Dvar1) Dvar2[ x], t);
  
  OPL/CPO may not give correct results. This is because the above
  usage (Dvar1 is a decicision variable used in a range for an all
  expression) is not supported and the syntax issue is not
  properly reported.
  

Local fix

• Reformulate the expression to avoid using decision variables in
  ranges.
  

Problem summary
