# General tab

The type of calculation variable is defined, as are the calculation basis, the compression level for the calculation result, and the calculation formula.

### Output format

Selection of the format of data output, from Numerical value or Time

### Calculation basis

Values up to the level of the respective calculation result are available to select the calculation basis:

<table><thead><tr><th width="182"></th><th></th><th></th><th></th><th></th></tr></thead><tbody><tr><td></td><td>Calculation result</td><td></td><td></td><td></td></tr><tr><td>Calculation basis</td><td>Interval value</td><td>Daily value</td><td>Monthly value</td><td>Annual values</td></tr><tr><td>Process values</td><td>x</td><td>x</td><td>x</td><td>x</td></tr><tr><td>Interval values</td><td>x</td><td>x</td><td>x</td><td>x</td></tr><tr><td>Secondary interval values</td><td>x</td><td>x</td><td>x</td><td>x</td></tr><tr><td>Daily values</td><td></td><td>x</td><td>x</td><td>x</td></tr><tr><td>Monthly values</td><td></td><td></td><td>x</td><td>x</td></tr><tr><td>Annual values</td><td></td><td></td><td></td><td>x</td></tr></tbody></table>

<details>

<summary></summary>

Calculation result = daily value

Calculation basis = process values

The first compression level is day data created from process values. The compression method required for this is selected on the Compression tab. As are the compression methods for any further compression levels.

Note

Additional compression levels can be activated in Plant Management/Database/[Compression levels](/acron-9.3/en/anlagenverwaltung/register-datenbank.md#verdichtungsstufen).

### Calculation result is temporary

Key figure that is not saved.

Note

You can use this option when calculating interim values that in turn are to be used by "normal" key figures. The calculation result is not saved.

### Key

Any entry capable of serving as a tool for filter conditions in the Form Designer, such as to hide or manipulate specific table rows.
