I am trying to get the MAX gift amount per person. Along with the corresponding gift code, gift designation, and gift date for that max gift. However when I put the MAX on the corresponding fields, it brings back the MAX based off of ABC order for that field. For example my max gift is 1000, with a designation of AFANNUAL. When I put the MAX on the desg field, it pulls back the designation with the latest letter of the alphabet, so let's just use ZEBRA as the designation. Also for the gift date, it is just bringing back the largest gift date, when I need the gift date of the largest gift. How can I achieve this?

The Max. designation only refers to the field on which it is placed, not the entire record. So for example, if you use MAX.MODEL and MAX.RCOST, you get the maximum value for retail cost, and the maximum (alphabetically last since it is an alpha field) value for model, but those two values will NOT correspond to the same record.

There are a couple of ways around this. One would be to sort by HIGHEST, HOLD, and then use the FST. prefix. This is the easiest/most straightforward, but requires a hold file.

You could also use a compute like

COMPUTE MAXGIFTDATE/YYMD=IF AMOUNT EQ MAX.AMOUNT THEN GIFTDATE ELSE '00000000';

(but then if there are two gifts with the same max value, there might be a problem.)

Third option is to use some combination of WITHIN in a COMPUTE to get the maximum value within a specific sort field.

Thanks so much! I knew there was a simple answer. I will use the first option. Thanks again, and have a good weekend!

You can also use BY HIGHEST 1. This approach does not require anything else. No hold as and fst.

But if you use BY HIGHEST 1, it has to be the highest 1 WITHIN the sort group - person in this case. Otherwise you just get one record returned. That was my last suggestion.
