I am struggling to figure out how to have a "master" listing of customers that can be referenced by various sheets via INDEX/MATCH cross sheet formulas when that list is too large.
Here is my background:
I have a master customer listing of 6200 customers. I use DataUploader to upload this into 3 sheets due to size limitations. I have various "Roster" sheets that lookup ~10 customers per sheet.
My issues:
1. I do not have a unique identifier in the excel (upload) file, but DataUploader must delete and add new rows, therefore my formula and/or system created ID just gets deleted.
2. I want to use a lookup (INDEX/MATCH) on each Roster sheet so that we can type in the full name of a customer and have cells populate (address, contact info, etc.). Even if I manually add my unique identifier formula into each sheet, I'm still unable to lookup against 3 separate sheets for each customer.
The only solution I am coming up with is to request a 1 sheet limit extension. Am I missing something else that can work?
Thanks in advance!
