Re-order Formula Report Columns

A non-Visualforce/Apex blog for a change this week. I was working on some reports for our Salesforce project management application, and needed to create a number of summary formula columns. Having created the first three, I wanted to change the order that these formula columns appeared in the report, and was surprised to find that this isn't supported through the UI - if you remove all formula columns from the report and add them back in, they are displayed in the order that they were created.   Searching on the Salesforce Idea Exchange only threw up this open idea.

Below is an example report I've put together to demonstrate this using Accounts.  I've added a single formula column that totals the account employees based on the country:

I then add a column to total the Annual Revenue, which displays to the right of the Country Employees column:

If I then decide that I'd like the Country Revenue column displayed first, the only way to achieve this through the UI is to delete the formula columns and recreate them in the desired order.  Maybe acceptable when there are only a couple of formula columns, but not an option once there's more than a handful.

Next up was to turn to the metadata API via the Force.com IDE.  As I'd just gone with the defaults when setting up the project, the only metadata components I had were Classes, Pages, Components and Triggers.  Right-clicking (or ctrl-click as I am now a Macbook Air user) the project name brings up the context menu for the project - selecting the Force.com menu followed by the Add/Remove Metadata Components brings up the following dialog:

Clicking the Add/Remove button (eventually) brings up a list of the available metadata.  Reports appears so I tick the entry for my report:

and click ok as many times as it takes to close the various dialogs.  When prompted, I select Yes to refresh the project.  Once the revised components have been pulled down from the server, opening the file associated with my report shows :

    <aggregates>
        <calculatedFormula>EMPLOYEES:SUM</calculatedFormula>
        <datatype>number</datatype>
        <developerName>FORMULA1</developerName>
        <isActive>true</isActive>
        <masterLabel>Country Employees</masterLabel>
        <scale>2</scale>
    </aggregates>
    <aggregates>
        <calculatedFormula>SALES:SUM</calculatedFormula>
        <datatype>number</datatype>
        <developerName>FORMULA2</developerName>
        <downGroupingContext>ACCOUNT.ADDRESS1_COUNTRY</downGroupingContext>
        <isActive>true</isActive>
        <masterLabel>Country Revenue</masterLabel>
        <scale>2</scale>
    </aggregates>

Looking promising - not only can I see the formula columns but they also have developer names that imply some sort of ordering. First up I tried changing the order that the columns appear in the XML and saving that. Unfortunately, this change was simply reverted when the file was changed.

Next, I changed the developerName for each column - changing the Country Employees to FORMULA2 and Country Revenue to FORMULA1. Looking better once the save completed - the ordering of the columns in the file had been reversed as shown below:

    <aggregates>
        <calculatedFormula>SALES:SUM</calculatedFormula>
        <datatype>number</datatype>
        <developerName>FORMULA1</developerName>
        <downGroupingContext>ACCOUNT.ADDRESS1_COUNTRY</downGroupingContext>
        <isActive>true</isActive>
        <masterLabel>Country Revenue</masterLabel>
        <scale>2</scale>
    </aggregates>
    <aggregates>
        <calculatedFormula>EMPLOYEES:SUM</calculatedFormula>
        <datatype>number</datatype>
        <developerName>FORMULA2</developerName>
        <isActive>true</isActive>
        <masterLabel>Country Employees</masterLabel>
        <scale>2</scale>
    </aggregates>

Encouraging, but the acid test is to re-run the report:

Success!  Comparing with the report screenshot above, the Country Revenue and Country Employees columns have changed places.  Not quite a simple as it might be through the UI, but certainly a lot quicker than deleting and recreating formula fields!
