PROBLEM GDX.xlsx (9.96 KB)
Hi Sema
You have the wrong extension in your code for the excel file: it is xlsx not xls.
I always add Trace =3 to the call, so I see directly if there are any errors.
If this is not the problem you are encountering (and I assume it is), gdx probably can’t find the gdx file after correctly generating it.
(probably you have forgotten to create a project for this gams file).
Be sure to send code that will produce your error (in your case it isn’t).
Cheers
Renger
