How to add a Calculation
Calculations (totals) are a required part of tagging. Including at least one calculation is essential to create the mandatory Calculation Linkbase, a crucial part of the ESEF report. Additionally, it serves as a tool for issuers to ensure they are reporting the correct XBRL values for the applied tags.
- Start by clicking on the cell that is the sum cell for the calculation you wish to carry out. Navigate to the Calculations tab and click on the button called "Select Summands: off" to switch it "on". The frame will turn green and the button text will change to "Select Summands:".
- Then select the cells that should be part of the calculation and click "Add selection". The selected cells should then appear in the bottom section of the window. Click the "Select Summands" button again to switch it off.
- Adjust the SignLogic if relevant. More information regarding SignLogic can be found here.
Calculation guidance
Why is my row marked in red?
- It is not possible to create a valid calculation that combines tags that have the Period Type Instant and Duration
- It could also be due to having an incorrect date set (in the properties tab) on either the calculating tag or on the tags added to the calculation.
Further guidance
If the value of a tag included in the calculation is 0, make sure the Number or Date Format in the properties tab is not set to “fixed-zero”.
