The concept is called By Group processing, in-built into Base SAS:

It is pretty simple. As you have 3 datasets, first combine them, and get this dataset name (dirst step below, the : means all datasets with that prefix), sort them just to make sure and apply the where, then print them by dataset name.
data want; length dataset $200; set eltm.mlt: indsname=tmp; dataset=tmp; run; proc sort data=want; by dataset; where cr_appl_no=60048444; run; proc print data=want; by dataset; run;
Do also note the consistent indentation, casing and such like in the code, it is very important to make code as easy to read as possible. And you don't need macro for this, or in fact any other task you will have to do. Macro is an additional text generation tool to save repeating code, it is not a replacement for Base SAS.
@RW9: I don't have 3 datasets, I have more than 50 datasets. How to combine more than 50 datasets. Could you show me by code please?
Thanks!
@Nancy05 Do all your tables have the same columns and same data types?
@Reeza Yes, My libname is correct and memname is starting with 'MLT'.
I have no problem of running this piece of code, and return the results I expected.
proc sql;
select distinct memname
from sashelp.vtable
where libname ='ELTML'
and upper(memname) like 'MLT%';
quit;
run;
I think the problem is with Cat function and not sure how to fix it.
@Reeza: No. Mylending datasets/table have different varibles/columns.
I have comment off STR1, but STR2 also not working... . probably need some space between words, not quite sure how.
Even @RW9 's method not sure it is works as I don't want all tables combined together (50 tables - more than 900 fields), it is too long to read, I like your second dynamic sql call and would like to make it working...
If your tables have different columns and variables then @RW9 solution won't work.
I modified the code above, it's tested and working.
The theory behind it is create a list of the tables using SASHELP.VTABLE to get the names.
Then generate a proc print using the table names and call execute. The strings you need to generate are easy, a title and proc print, with only the table name changing. The table name comes from the table list.
Good Luck.
1. Add SET statement to data _null_ so the table is being used
2. Modify the STR1 to generate the TITLE statement correctly.
This is tested and working.
%macro print_report(CR_APPL_NO);
%*Get all table names from library that start with MLT;
proc sql noprint;
create table table_list as
select distinct memname
from sashelp.vtable
where libname='ELTML'
and upper(memname) like 'MLT%';
quit;
%*use Call execute to print each table for specified record;
%*I create the strings as an extra step to allow for debugging;
%*You should remove the PUT statements after you have this working;
data _null_;
SET TABLE_LIST;
str1=cats( "Title 'Mylending Tables-", upcase(memname), "';");
str2=cat("Proc Print Data=ELTML.", memname, "NOOBS;", "Where CR_APPL_NO=&CR_APPL_NO; RUN;");
put str1;
put str2;
call execute(str1);
call execute(str2);
run;
%mend;
Thanks everyone who answered my question! Especially, a big thank you to you, @Reeza. This is a piece of elegent code. This is exactly what I want. Simple and effcient! Really awesome.
