I need to find the most recent transaction; a single invoice can have many post dates, some are the same date; the duplicate post dates have unique line item entry numbers. I know I can identify the row with the most recent post date, HOLD it, and then find the highest line item number, but is there is a way to do this in a single step? My goal is to extract the value in a different column, based on most recent post date and highest line item number.

Thank you

What is the datasource ?

If you use TABLEF and PRINT, you will get the record in order of storage, it then depends on whether the storage order is correct.

I suppose you could use:
BY HIGHEST 1 POSTDATE
BY HIGHEST 1 LINENO

A test is in order...

As WAZ says, to give a good answer, one has to know the data source.

Pretty close. I am using:
PRINT
'MAX.DM_FACT_INVOICE.DM_FACT_INVOICE.POST_DATE' NOPRINT
BY 'DM_FACT_INVOICE.DM_FACT_INVOICE.INVOICE_NUM'
BY HIGHEST 1 'DM_FACT_INVOICE.DM_FACT_INVOICE.POST_DATE'
BY POST_DATE

But I am still getting a blank row where there was a 'duplicate' post_date. I need to eliminate the blank rows, I've tried a couple of of different sorts and "highest already. When this is working, I'll add the line item number.

Any suggestions?

Make a define field that concatinates the two abnd take the MAX. Should work in most datasources (though you should check the generated SQL).

PRINT
'MAX.DM_FACT_INVOICE.DM_FACT_INVOICE.POST_DATE' NOPRINT
BY 'DM_FACT_INVOICE.DM_FACT_INVOICE.INVOICE_NUM'
BY HIGHEST 1 'DM_FACT_INVOICE.DM_FACT_INVOICE.POST_DATE'
BY POST_DATE

A couple of comments:

- The "MAX" won't do anything here.
- The HIGHEST 1 won't do anything here, unless DM_FACT_INVOICE.DM_FACT_INVOICE.POST_DATE is a different column than POST_DATE.
- The "blank rows", are they really blank, or are they simply blank sort field values?

If you need the latest date for each invoice number, have you tried:

SUM
INVOICE_NUM NOPRINT
BY INVOICE_NUM
BY HIGHEST 1 POST_DATE

I'm not seeing any reference to line number in your code. The earlier post by Danny-SRL about using BY HIGHEST 1 should have done the trick.

This is the final working result:
PRINT
INVOICE_NUM NOPRINT
CUR_FSC_CD
INVOICE_BAL
BY INVOICE_NUM
BY HIGHEST 1 POST_DATE NOPRINT
BY HIGHEST 1 LINE_ITEM

I will also try the idea with the DEFINE to concatenate two columns and see if its faster.

thank you
