Hi I need help with the following I need to take a value from a past date if a line item with a list format matches with another one, i Mean for example as you can see in the attached image. I have time ( in dates format ) and in a colum with a list formatted (DIA), but i need to change the amount and to use an amount that match with a prior date. So for example on Jan 7th the loaded data is 76,659 but i need to use the amount of Jan 2nd, as you can see I should expect to get 94,531 if the column "DAY1" matches with "DIA"
