Program running fine and resolve this issue..can anyone says why call symput (ID_start & ID_end) value may not able to resolve...my question here if I created loop macro variable using call symput which is easily coming during the program even though did not modify any syntax..

I would suggest that this condition:

if week_id= &start_wk then do;

doesn't resolve at any point to be true, hence the call symput is not run and ID_START is never defined. The likelihood is that the call:

%let startwk =201425;

%let endwk =201428;

%bci_period(&startwk,&endwk);

when looked in combination with the if statement resolves to:

if week_id=201425 then do;

Which doesn't work. If your sure that week_id is character and contains a value for 201425, then put quotes around the macro variable and retry:

if week_id="&start_wk." then do;

This should then find a row.

However if week_id is numeric then you may need to convert it to the numeric type of week_id, e.g.

if put(week_id,yymm6.) = "&start_wk." then do;
