Nested Loop and splitting

LB — Wed, 18 Apr 2018 23:14:57 GMT

Hi all;

So I am attempting to run macro loops within each other-

In this example I am using the sashelp.baseball dataset as I can't use company data but the concept and results are the same-

So in this case-the first loop outputs data from the league (American,National) and outputs via proc report into separate excel documents. This part works fine-

It's the nested loop that becomes the issue where for each league report-I am attempting to output a proc shewart graph for each team in the league on separate tabs-

However, while it produces separate excel workbooks for each league, it simply repeats the same team shewart graph for each tab.

(ie. for the National League it outputs Chicago 12 times)

I am sure I am missing something simple.

Code follows below-

Assistance much appreciated.

proc sort data=SASHELP.baseball out=BASEBALL;
by YrMajor;
run;
%macro ambulA (data=, var=);
proc sort data=&data(keep=&var) out=values nodupkey;
by &var;
run;
data _null_;
set values end=last;
call symputx('facid'||left(_n_),&var);

if last then call symputx('count1',_n_, 'g');
run;
%put _local_;

DATA _NULL_ ;
select(&var);
%do i=1 %to &count1;

options center;
ods listing close;

Are you sure the code you posted can be executed without error?

(It is highly recommended that you post your code with 'Insert sas code' commad so that it can be more readable.)

I can't run you code but I think the reason might be the macro call in the inner loop is only pushed into a stack and won't be executed until the data step is completed.

Try 'call exectute' or 'dosubl'.

Your syntax is invalid. Why do you have these?

DATA _NULL_ ;
select(&varx);

remove these and try.

Title "&&unit&i Control Chart";

proc shewhart data=toch (where=(TEAM="&&unit&i"));
xchart nruns * YrMajor/nolegend MARKERS ;
run;

You need to have "j" instead of "i" here.
