f you want to see change/development in an accounting account or key figure, you can create a formula and then enter the unit as a percentage. It is suggested to define it as the current month's value minus the previous month's value by the previous month's value. To get the previous month's value, use "Prev()" as below.
If the account is 3046, the formula is as follows:
(-{3046}-Prev(-{3046}))/Prev(-{3046}
In the same way, it is possible to create a formula with an uploaded CPI. If the CPI is called balance units, for example, then the formula becomes:
((balance units-Prev(balance units))/Prev(balance units)
Finally, % must be selected as the unit. You do this under "Appearance", then select "Unit" and %. Remember to save and it's done.
