Hi fellow SAS-users!
After much frustration and a lot of reading up on the proc optmodel and examples I turn to you.
Essentially I am trying, by using sets, to read in some data which varies in the number of elements in several dimension. A simplified example of what I want would is:
data Company_Data;
input Customer Bill;
datalines;
cust1 B1
cust1 B2
cust1 B3
cust2 B4
cust3 B5
;
proc optmodel;
set<string> Customers init {};
set<string> Bills{c in Customers};
read data Company_Data into Customers=[customer];
/*Magic to get Bills read into the model */
?
?
?
/*What I want*/
Customers={'cust1','cust2','cust3'};
Bills['cust1'] = {'B1', 'B2', 'B3'};
Bills['cust2'] = {'B4'};
Bills['cust3'] = {'B5'};
/* End of model */
