Hello guys,

I have below data set in which i want the values of reason in one record by subject & Visit description.

Subject	Visit_description	Start_date	End_date	Reason	Other_Reason
1	Assessment 1	6/26/2020	6/26/2020	CONVULSIONS
1	Assessment 1	6/26/2020	6/26/2020	DEHYDRATION
1	Assessment 1	6/26/2020	6/26/2020	FEEDING DIFFICULTY
1	Assessment 1	6/26/2020	6/26/2020	OTHER	iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
1	Assessment 2	6/27/2020	6/27/2020	IRREGULAR OR PERIODIC RESPIRATION
1	Assessment 2	6/27/2020	6/27/2020	IRRITABILITY OR AGITATION
1	Assessment 2	6/27/2020	6/27/2020	LETHARGY OR EXCESSIVE SLEEPINESS

Output should be like below table

Subject	Visit_description	Start_date	End_date	Reason	Other_Reason
1	Assessment 1	6/26/2020	6/26/2020	CONVULSIONS,DEHYDRATION,FEEDING DIFFICULTY,OTHER	iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
1	Assessment 2	6/27/2020	6/27/2020	IRREGULAR OR PERIODIC RESPIRATION,IRRITABILITY OR AGITATION,LETHARGY OR EXCESSIVE SLEEPINESS

Try next code:

data want;
 set have(rename=(reason = _reason));
  by Sunject Visit_desription;
     retain reason;
	 length reason $100; /* adapt to max neaded */
	 
	 if first.Visit_desription then reason = ' ';
	 reason = catx(',',reason,_reason);
	 if last.Visit_desription then output;
run;

Very bad answer, totally unhelpful.

Please describe in detail what "did not work".

Did you get ERRORs or WARNINGs? Or did the code run, but not produce the expected output?

In all cases, post the log, using the </> button. Point out the difference between expected and actual result.

Providing example data in usable form (self-contained data step) is also a MUST if you want quick answers with a valid solution.

Sorry for that..
This warning i got and output is not matching..

WARNING: In a call to the CATX function, the buffer allocated for the result was not long enough to contain the concatenation of all the arguments. The correct result would contain 5
characters, but the actual result might either be truncated to 1 character(s) or be completely blank, depending on the calling environment. The following note indicates the

By "post the log" I meant to post the whole log of your step, including the complete code of the step and all follow-up messages. And, as requested, you must (MUST) use the </> button to keep the formatting of the log. This is important, as the horizontal position of ERROR markers helps in identifying the cause of an ERROR, and this positioning is destroyed by the main posting window.

If you check the posted code it written explicitley:

length reason $100; /* adapt to max needed */

I cannot know what is the maximum number of reasons will be concatenated.

You can change the length to 1000 up to 32000 but better evaluate it or just increase until there will be no more such warnings.

Do you need or prefer sorting the concatenated reasons or leave them in order as they arrived? Can there be a reason more then once per subject?
