Dear All,

I am working with a coverage set problem in IBM ILOG CPLEX studio, when I am loading data from excel into OPL this message pops up.
“exception from ibm ilog concert: cannot read data from excel”
P.S. my excel data is huge (a network of 8459*8459 nodes) and when I try the model with a small chunk of the data, it works fine.
I wonder if this problem is to do with the limitation of CPLEX studio to handle large dataset or anything else could happen.

I would appreciate for any hint.

regards.
