The only thing I'm asking for is that you post a SAS data step which creates for us sample data.
Something like:
data have;
infile datalines dsd dlm=',' truncover;
input mothercust_id cust_id org_nr;
datalines;
1,11,1234
2,22,1235 ...all the other observations as shown in your screen shot
;
run;
If you've got already a SAS data set then you can also use the link @RW9 posted to create such a SAS data step
