How can I edit data for a single field entry?

hellyars

My data has a few dollar entries that need to be corrected for a given year's spend.  The original data is embedded deep within an XML file, so I can't correct it there.  How can I do this within the workflow?  My output is typically a Tableau TDE file.  And, I would prefer not to have an interim Excel export/import step or two.  Thank you.

If you know the exact entries you need, you could use a Filter, Formula, then Union.  The filter grabs just the record you're correcting, the formula makes the change, and the Union adds it back to your data.  Unfortunately you'd need to repeat this process in your flow for every correction you needed to make:

Alternately, you could make a large IF statement in a formula:

Or, if you have the list of corrections, do it through a join:

A lot depends on your actual data, but hopefully this gets you going in the right direction.
