Analytical dimensions of the invoicing element.

The analytical dimensions are initialized according to the setup of Default dimensions (POV dimension code), associated with the management of invoicing elements. These dimension codes can be modified manually if authorized by the transaction. Use the Actions icon to change the dimension codes of the dimension types.

When an analytical dimension type is used for the Project management tracking, any modification of the project code on the document header leads to the dimension code being reset for this dimension type, except if a distribution key has been entered.
