Custom Columns and Units
Defining Custom Fields
Requirements Portal already offers a great variety of columns to describe your Requirements. However, if your use-case requires a specific column with a specific name, you can add additional columns called Custom Fields or Custom Columns.
Workspace Administrators can review defined custom fields and create new ones on the Settings – Custom Fields page (accessed by clicking the 
icon at the top right, selecting Settings from the menu that appears, and then selecting Custom Fields from list in the left-hand pane).
Sorting and filtering can be applied to the list of custom fields.
-
Click on a column heading to sort the list of custom fields by this column. Click once to sort in ascending order (based on the content of that column). Click again to sort in descending order. Click again to remove sorting.
-
Hover the cursor over a column header, click the
icon, and then click the 
icon in the popup that appears to access filter options.
To create a new custom field, click the 
button at the top right. The Create Custom Field window will open.
The Create Custom Field window provides the following options:
-
Name – the name of the column that will appear as a header in the table.
-
Projects – the project(s) where the custom field can be used.
-
Target:
-
Requirements – a custom field in the Requirements Module is created.
-
Activity – a custom field in the Activity is created.
-
Activity Run – a custom field in the Activity Run is created.
-
-
Field Type:
-
Text – Rich Text field column.
-
Select – single select from a drop-down menu.
-
Date – date/time select from a calendar pop-up.
-
Number – only allows numeric entries to the column.
-
Multi Select – multi-select from a drop-down menu.
When selecting Select or Multi Select as the Field Type, you will be prompted to define the individual Field Options from which to choose in the drop-down menu.
-
Once the options are configured as required, click the 
button. An entry of a newly created custom field will appear on the Settings – Custom Fields page.
Defining Custom Units
The calculation engine of Requirements Portal already comes with a well-defined set of units, which are clearly defined by the employed Pint Library. However, there might be a situation where very specific units need to be defined that are not yet handled by the calculation engine. A specific use-case would be a currency with a specific conversion.
Workspace Administrators can review defined custom fields and create new ones on the Settings – Custom Units page (accessed by clicking the icon at the top right, selecting Settings from the menu that appears, and then selecting Custom Units from list in the left-hand pane).
To create a new custom field, click the 
button at the top right. The Create Custom Unit window will open.
A custom unit must always be defined based on an already existing unit, for instance:
apple = 0.5 * kg = ap
This entry creates a unit called apple which converts to half a kilogram. With this entry the calculation engine will recognize apple and ap as units that can be used for Valis.
