Symptom
- In planning, inverse formulas on calculated KPIs do not behave as expected and the cells remain non-editable in specific input scenarios.
- The behavior affects several calculated KPIs, while a comparable KPI with a similar setup may work as expected.
- In some contexts, the table shows the message “Inverse formula is missing”.
- In some periods, the table shows the message “Exception aggregation on a formula member”.
- The issue is observed when attempting direct input on a story table.
Environment
SAP Analytics Cloud
Reproducing the Issue
- Open a planning story that contains calculated KPIs with inverse formulas.
- Navigate to the planning table where the KPIs are displayed
- Attempt to input a value directly into a calculated KPI that has an inverse formula defined.
- Observe that the input is disabled and/or messages such as “Inverse formula is missing” or “Exception aggregation on a formula member” appear.
Cause
- The inverse formula chain is incomplete: one or more nested dependent calculations referenced by the target formula do not have their own inverse formulas, which prevents input enablement.
- In some periods, the member is unplannable due to “Exception aggregation on a formula member”.
- Story-level calculated measures and accounts are not subject to model data locking, so editability in-table may not reflect lock status; locks are enforced at publish time.
Resolution
- Verify all nested dependencies of the calculated KPI and ensure every referenced calculated measure/account has its own inverse formula, even if it isn’t the direct target of the outer formula.
- Add the missing inverse formulas to each dependent calculation in the chain so the inverse path is complete from the edited KPI down to plannable base data.
- Review any members using exception aggregation on a formula member. If present, redesign to avoid applying exception aggregation on formula members for periods where input is required, or enter data at the appropriate base level.
- Re-check input enablement in the story table after completing the inverse chain and adjusting exception aggregation as needed.
- Consider data locking behavior: model-level data locks do not directly restrict story calculations; locks are validated at publish time. Test by publishing changes and align design accordingly.
