Hey there,
Just curious that how can I use some filter to create a dataset that only contains positive decision variables in proc optmodel like following
proc optmodel;
...
solve;
create data Solu from [a b c d]X (here I want to apply a filter such as X[a b c d] > 0)
quit;
since my dataset is relatively large, this would greatly reduce redundant information and save the space.
Thanks in advance!!!!
