Field help (LEGINVCND) 

In creation mode, the legislation code can be initialized via the user parameter LEGFIL - Legislation (selection filter)(SUP chapter, INT group). You can also use this parameter to filter the selection panel and only display the codes defined for this legislation and those defined at the All legislations level.
You can enter a specific legislation so as to limit the use of the invoicing term only to documents linked to companies of the same legislation.
