You may try the following with SQL.

Exec SQL Set :My20st = Last_Day(Current_Date) + 20 Days;

Betreff: Re: Calculate the 20th of next month

I actually just went through this last week.

I ended up using a character date and the substring BIF. This is what
concerned me from the documentation.
"Adding or subtracting a number of months to the 29th, 30th, or 31st day of
a month may not be reversible. For example, 2000-03-31 + %MONTHS(1) -
%MONTHS(1) is 2000-03-30. "

While it might be the 20th now, you never know when that could change and
someone would just replace the number 20 with what they desire.

I created a simple subprocedure that excepted a date, converted it to a
character date, substring the fields you want to change and create a new
date.

charDate = %char(date : *iso);
%subst(charDate : 7 : 2) = '20';
newDate = %date(charDate) - %months(1);
return newDate;

HTH,
