In this case we show the ways this range can be defined
When using a single number (i.e. 4) all accounts starting with a 4 will be selected (from 400000 to 499999)
In this case all accounts starting with 40 or 44 will be selected, this means all accounts from 400000 to 409999 and all accounts from 440000 to 449999.
Defining your range like this will make sure that all accounts from 400000 to 449999 are selected
Ofcourse it’s possible to combine several of these methods
In this case, all 40 accounts (400000 to 409999), all accounts from 540000 to 589999, all accounts from 491000 to 491999 and finally also the accounts from 493000 to 493999 are selected.
That wraps it up.
If you still have questions about this subject, you can always ask them here.
Where did you allocate the range in your report? Are you using formulas? If you just want to get the value os that specific account it might be work just to use the drag and drop functionality as in the image below:
