Hi all, somehow I can't calculate the months between 20211231 and 20230228. Code:Copy to clipboard %let End = %sysfunc(intnx(month,%sysfunc(today()),-4,e),YYMMDDN8.); %let Begin = %sysfunc(intnx(year, %sysfunc(date()), -2, e),YYMMDDN8.); %put &Begin; %put &End; %let count_months =%sysfunc(intck(month,&Begin.,&End.)); %put &count_months; I get the following log statement: WARNING: An argument to the function INTCK referenced by the %SYSFUNC or %QSYSFUNC macro function is out of range.

Many thanks in advance. Kind regards, Ben ... View more
