I have a column which displays the actual sales day bay day. I would like to have a column which takes the average of last seven days (Rolling Average)? As a result the first 6 row is missing and the data starts on 7th fo the first 7 days mean at 8th the 2nd to 8th rows mean, at 9th the 3rd to 9th mean...and so on
many thanks in advance
Would you please show me how to add "by variable" to the script above?
Sales by Year,
Sales by Year by Agency
Sales By Year by Agency by Month...
Many thanks in advance
