Either that (subject line), or I just don't understand how to use it. I found it to be really frustrating, but here's my problem.

I have 2 tables.....RPRARSC with 964 ID's (based on selection critera) and RPRAWRD with 11,195 ID's. Now, most of RPRARSC's ID's are in RPRAWRD, so I want to select all of the ID's that exist in RPRARSC and NOT in RPRAWRD. So I resort to matching. Here is my code.

MATCH FILE RPRARSC
  BY RPRARSC_PIDM
  WHERE RPRARSC_AIDY_CODE EQ '0607'
  WHERE RPRARSC_EST_AMT GT 0
RUN
FILE RPRAWRD
  BY RPRAWRD_PIDM
  WHERE RPRAWRD_AIDY_CODE EQ '0607'
  WHERE RPRAWRD_ACCEPT_AMT GT 0
AFTER MATCH HOLD OLD-NOT-NEW
END


When I run the report below based on this, I get a distinct count of 964. This is not the correct answer. I've tried different variations of the MATCHING wizard's merge phrases, but I still come up with the same number. I run this in SQL using the MINUS statement, and I get 354. I've also run this a few other ways and 354 is the correct distinct count. 

TABLE FILE HOLD
SUM
     CNT.DST.RPRARSC_PIDM
ON TABLE NOTOTAL
END


I'd love to know what I am doing wrong with MATCH, even if there is a better way to do this, if it's possible.

Thanks,
Brian

Match...
print ...
by ...
run

You are not following the syntax correctly. Match file requires the by fields from each file to named the same and also have the same format. Assuming the formats are the same you need to us an as phrase for one of your by fields like this. If the formats are not the same then a Define is needed to one of the by fields to make them the same.

quote:
MATCH FILE RPRARSC
BY RPRARSC_PIDM
WHERE RPRARSC_AIDY_CODE EQ '0607'
WHERE RPRARSC_EST_AMT GT 0
RUN
FILE RPRAWRD
BY RPRAWRD_PIDM as RPRARSC_PIDM <================
WHERE RPRAWRD_AIDY_CODE EQ '0607'
WHERE RPRAWRD_ACCEPT_AMT GT 0
AFTER MATCH HOLD OLD-NOT-NEW
END


Good luck

ET, that worked great. Now I am getting the correct number. I appreciate your quick response. Also, thank's for the suggestion Leah. I did try that though.
