Hi, I am reading an MPS file using this code. I got this code from this link. https://documentation.sas.com/?docsetId=casactmopt&docsetTarget=casactmopt_optimization_examples06.h...

 

proc cas;
example_fix_string = readpath ("&filepath."); 
loadactionset "optimization";
action optimization.loadMps /
mpsFileString = example_fix_string
casOut = {name = "example_fix" replace = true}
format = "FIXED";
run;
action table.fetch / table = "example_fix" to = 24;
run;
quit;

 

However, I get this error as shown in below error log. I wonder how to fix?

 

30 proc cas;
31 example_fix_string = readpath ("&filepath."); 
32 loadactionset "optimization";
33 action optimization.loadMps /
34 mpsFileString = example_fix_string
35 casOut = {name = "example_fix" replace = true}
36 format = "FIXED";
37 run;
ERROR: The server connection has not been specified
ERROR: Execution halted
38 action table.fetch / table = "example_fix" to = 24;
39 run;
ERROR: There is no server connection to execute the action 'table.fetch'.
ERROR: Execution halted
40 quit;

I suspect that you have SAS/OR (SAS 9) and not SAS Optimization (SAS Viya).  If that is true, please try this example instead:
