The analytical dimensions are initialized according to the Default dimensions setup, associated with the management of quote headers. 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 based on the Default dimensions setup. If the project code is used on the lines, the dimension code of the impacted lines is also reset.
