Hello Jeylan
I am V. Arya, Independent Advisor, to work with you on this issue. The limit is 200 variable cells. Excel solver will not be able to handle more than this.
You will need to break your problem in chunks if possible in your case. Otherwise there is a paid solver product (solver was incorporated into Excel by Microsoft from this company only) which has a limit of 2,000 decision variables for linear problems, and 500 variables for nonlinear problems
