Analytical dimensions of the invoicing element.
The analytical dimensions are initialized according to the setup of Default dimensions, associated with the management of invoicing elements. Depending on the setup, they remain available for modification.
When an analytical dimension is used for project management tracking, any modification of the project code on the document header leads to the dimension code being reset, except if a distribution key has been entered.
Use the Actions icon to change the dimension codes of the dimension types.
