PROC SQL NOEXEC; SELECT (MAX(CASE WHEN(d1= 'C' AND d2= 'X') THEN sutun1||' '||sutun2 ELSE ' ' END)) AS CALCULATION FROM BB2.Ott t1; QUIT;
ERROR: Concatenation (||) requires character operands.
what's my fault?

Exactly what it says, your variables should be character but they're numeric.
You can use CATX instead, but it converts numbers using the BEST format so verify it gives you what you want.

What is it your actually trying to do as there are various issues with your code. First, you have the problem as given by @Reeza, you are concatenating (a string function) numeric variables. Secondly, you are max()ing (a numeric function) on character data.
Provide a small bit of test data and show what you want out, maybe something like:
proc sql noexec; select max(coalesce(SUTUN1,SUTUN2)) as CALCULATION from (select * from BB2.OTT where D1="C" and D2="X"); quit;
