data yourdata; set yourdata; array change _numeric_; do over change; if change=. then change= NA; end; run ;
The above sas code does not work as i am trying to replace missing Numeric variable value with NA

No, That's not how a user defined format works. Post your code if you're having issues.
Even after using user defined format .....The format of all numeric
variable changes....hence the data does not show correct value

Well, a column is numeric or character and NA is a character. So you're trying to put a character in a field that expects a number.
Do you need NA to export it to R?
How are you exporting, perhaps modify it there?
What you're trying to do overall will define how this should be approached.

User defined format solves your problem. See below code
PROC FORMAT ; PICTURE Num .="NA" OTHER="00.00"; run; data test; input Number ; format Number num. ; cards; 3.3 6.8 10 . run;

Defining your own numeric format is the simplest way to replace the printed values:
data test; do x = 1, ., .a, ._, 2; output; end; run; proc format; value myMiss . = " NA" other = [best12.]; run; proc datasets library=work nolist; modify test; format _numeric_ myMiss.; run; proc print data=test; run;
Note that special missing values are not affected by the custom format as defined above.
