Get the most recent target for each date

[dgyorfi]

Hi all, I have the following problem:

I have a table with campaign target information but I only have data points for the days when a campaign started and when the target of a campaign was changed, so not every day.

I have another table with daily campaign performance information and I would like to somehow assign a target value to each day of the campaign, basically looking up the target value of the most recent campaign change date or alternatively the starting target. The two tables are joined through dimension tables (partner / country / date) and that's the granularity I'd like to have the metrics calculated on.

Thanks a lot for your help, if you need more info please let me know!

Will it be possible for you to post some sample data and your expected result set?

Thanks
