Hello Community. I need some help identifying the best way to update records. I appreciate any help getting to a solution.
Situation:
I have 30k + accounts in my production environment. We want to load previous year sales data into a field within each account record. There is a unique identifier in the account number. Obviously you cannot just import and run a lookup field to them as the import wizard does not allow this... To my knowledge? please correct if I am wrong.
My thinking was to use the Upsert code function. Has anyone used these successfully? Are there any documentation that details this process start to finish?
Another option would be to export to excel online and run some sort of Vlookup to the correct account. Has anyone mass updated 30k + records like this via excel online? I think it would not handle that amount of data very well?
Thanks everyone and I appreciate your help!
