## Comparing quarterly sales data to previous quarter and previous year.

### Comparing quarterly sales data to previous quarter and previous year.

I have created a query that examines qarterly sales for 5 regions in
the country. The query contains data for the past 6 quarters for each
region and calculates the perecentage of total sales for the quarter
fo each region.

To help enhance the report I would love to include a comparison to of
current sales to previous quarter sales and a comparison of current
sales to sales a year ago. I am having a devil of a time creating a
query to perform those actions. I am not skilled at VBA and was
hoping someone could provide me with the code that will make the
comparisons.

Below is the all of the data in my query.

Your help would be greatly appreciated!!

### Comparing quarterly sales data to previous quarter and previous year.

lt;<I have created a query that examines qarterly sales for 5 regions in the
country. The query contains data for the past 6 quarters for each region
.....>>

You must have some criteria in the query that starts with today and goes
back 6 quarters from there. Since you want to add comparison to sales a year
ago, change the criteria so it only goes back 4 quarters. Then make a copy
of the query and in the copy, change the criteria so the copy starts with
the date a year ago today and goes back 4 quarters from there. Create a
union query from these two queries. The union query will then contain the
sales from the past 4 quarters as well as the four quarters previous to
that. You would create a crosstab query then for your form or report. To get
the comparison of current sales to previous quarter, do the calculation
directly on the form or report because both values will be there from the
union query. Your form or report will then look like the following assuming
3Q04 is the current quarter.:

4Q03 1Q04 2Q04
3Q04
Current Year 5MM 4.8MM 6.2MM
6.7MM(+.5MM)
Previous Year 4.3MM 5MM 4.8MM
5.8MM
