In the attached spreadsheet you will see that there are three columns (Loan Number, TransID, and Related). What I would like for SAS to be able to do is to link every Loan Number that has the same TransID and put them in the Related column with a comma in between each one. So that if Loans COMM01 and COMM02 had the same TransID, in the Related column it would read COMM01, COMM02 for both of those loans.
Loan Number | TransID | Related |
COMM0001 | 560 | COMM0001, COMM0002 |
COMM0002 | 560 | COMM0001, COMM0002 |
COMM0003 | 1727 | COMM0003, COMM0004 |
COMM0004 | 1727 | COMM0003, COMM0004 |
COMM0005 | 3032 | COMM0005, COMM0006 |
COMM0006 | 3032 | COMM0005, COMM0006 |
COMM0007 | 3591 | COMM0007, COMM0008, COMM0009, COMM0010 |
COMM0008 | 3591 | COMM0007, COMM0008, COMM0009, COMM0010 |
COMM0009 | 3591 | COMM0007, COMM0008, COMM0009, COMM0010 |
COMM0010 | 3591 | COMM0007, COMM0008, COMM0009, COMM0010 |
COMM0011 | 3971 | COMM0011, COMM0012, COMM0013, COMM0014, COMM0015 |
COMM0012 | 3971 | COMM0011, COMM0012, COMM0013, COMM0014, COMM0015 |
COMM0013 | 3971 | COMM0011, COMM0012, COMM0013, COMM0014, COMM0015 |
COMM0014 | 3971 | COMM0011, COMM0012, COMM0013, COMM0014, COMM0015 |
COMM0015 | 3971 | COMM0011, COMM0012, COMM0013, COMM0014, COMM0015 |
