fastest way to retrieve saved data for editing.

[foxguy]

What is the quickest way to retrieve data from a "Saved Data" sheet and put it into a "Data Entry" sheet for editing?

The Saved Data sheet has 3 columns; 1) Date, 2) Product Key, and 3) Amt Sold. Columns 1 & 2 form a unique key for each row. There are currently over 40,000 rows of Saved Data. There are rows only for Products that have been sold (IOW no "0"s in the Amt Sold column).

The Data Entry sheet has over 200 rows of Products.

I have done this several times, but never with so much Saved Data and I'm concerned that my usual method of retrieving data will be too slow. I usually have a column ("Saved Data") on the Data Entry sheet with formulas to look for the values on the Saved Data sheet so when the user enters a date, Worksheet_Change() copies the data from the Saved Data column into the editing column.

I would prefer to just use formulas to locate the data to retrieve. I would also like to avoid having "N/A" anywhere in the worksheet.

Use a userform (what's in a name ?)

I still have to retrieve the data to put into the userform. Not every field in the userform can be attached to a cell. If a product has not been sold yet, there will not be a cell to edit.

To best describe or illustrate your problem you would be better off attaching a dummy workbook, the workbook should contain the same structure and some dummy data of the same type as the type you have in your real workbook - so, if a cell contains numbers & letters in this format abc-123 then that should be reflected in the dummy workbook. Don't upload a picture when you have a workbook question. None of us is inclined to recreate your data. Upload the workbook and manually add an 'after' situation so that we can see what you expect. In addition clearly explain how you get the results..
