Hi I am trying to solve an LP problem in GAMS (I can only use GAMS). I am new to the optimization work. So I am seeking advise on what all I could/should check for in my code if I get the following message on solving my problem (has 20 variables and 38 constraints- I know seems too many). Also I am solving it like an inventory problem where people from previous year need to be counted in the current year to find current year value.
