How to use "create data" statement in proc optmodel

[lpy0521]

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!!!!
