6 months back

[Tal]

%let YTD_START = %sysfunc(intnx(year.11, &LASTFRI, 0),yymmdd10.);

this above gives me YTD_START='2023-11-01'  beginning of  fiscal year but  when i am  trying to get the date 6 months prior  to fiscal year  (below)

%let back_6months= %sysfunc(intnx(month,&YTD_START,-6),yymmdd10.);

i am  getting back_6months=1965-01-01.  What do  i have wrong here?

Remove the format from the %let YTD_START = statement.

%let YTD_START = %sysfunc(intnx(year.11, &LASTFRI, 0));

Why? Because to do arithmetic or logical operations on macro variables whose values are dates or time or date/times, the value in the macro variable must be unformatted. See Maxim 28.
