Hi,

I have a data something like this

ID	Visit date	Gender of Sex partner
11263	9/1/2017	2
11263	9/6/2017	9
11263	9/13/2017	9
11736	9/4/2018	1
11736	9/14/2018	9
11891	6/6/2017	9
11891	7/17/2017	2
11891	8/2/2017	2
11894	8/9/2017	9
11894	9/18/2017	9
11893	9/21/2017	3
11893	10/20/2017	9

gender of sex partners(gender_sp) code is 1=male, 2-female, 3=both, 9=unknown

I want to copy mostly prior visit's gender of sex partners' info to other visits . in some situation gender of sex partner is missing in fist visit but is available in second visit. I want to copy gender of sp to all visit if it is the same patient. How can i do this? I have 9588 records cannot fix this manually. Please help. SAS community is a GREAT resource for me.

i want like this from the previous table

ID	Visit date	Gender of Sex partner
11263	9/1/2017	2
11263	9/6/2017	2
11263	9/13/2017	2
11736	9/4/2018	1
11736	9/14/2018	1
11891	6/6/2017	2
11891	7/17/2017	2
11891	8/2/2017	2
11894	8/9/2017	9
11894	9/18/2017	9
11893	9/21/2017	3
11893	10/20/2017	3

It would help if you provided data following these instructions so we could test out the results.

https://communities.sas.com/t5/SAS-Communities-Library/How-to-create-a-data-step-version-of-your-data-AKA-generate/ta-p/258712

As it is, I can't test my code on your data, so consider this to be UNTESTED CODE

proc transpose data=have out=have_t;
    by id;
    var gender_of_sex_partner;
run;
data have_t2;
    set have_t;
    gender_of_first_partner=coalesce(of col:);
run;
data want;
    merge have have_t2(keep=id gender_of_first_partner);
    by id;
run;

If it doesn't work (because it is UNTESTED CODE), please provide (a portion of) your data in the format requested.
