WebFocus Record Retrieval W/most current date

I am trying to pull active records from a table and I need the most current date. There may be more than one active record for a person and as it stands the report is just pulling one. Is it possible to set it to pull the most current? However, I noticed that the most current may not be the last record for each person (so they are not stored in date order).

Claudette,

You can use BY HIGHEST 1 datefield. However make sure your placement of the BY is correct as the following example against the GGSALES file.

Note that the first table request holds data with a random number so that I can randomly leave out data from the reports.

The second report shows the data with the data holding a random number less than zero removed.

The third report shows what you are after and you can verify this against the second report.
TABLE FILE GGSALES
SUM DOLLARS
    COMPUTE Rdm_Numb/D12.2 = RDNORM('D12.2');
BY ST
BY REGION
BY DATE
WHERE DATE FROM '01011996' TO '31121997'
ON TABLE HOLD AS HGGSALES
END
-RUN

TABLE FILE HGGSALES
SUM DOLLARS
BY ST
BY REGION
ACROSS DATE
WHERE Rdm_Numb GE 0
END
-RUN

TABLE FILE HGGSALES
SUM DOLLARS
BY ST
BY REGION
BY HIGHEST 1 DATE
WHERE Rdm_Numb GE 0
END
-RUN


Enjoy

I usually use a sort on a date with the BY HIGHEST and compute a value for a WHERE TOTAL test when there is no other way. Other selection present of course so you don't pull the entire data. Of course you could select on MAX.date, however doesn't mean the other data would tie to the date.
