Field help (TYPGFY)

By entering a company group, you can limit the scope to companies in the selected group only. When this data is used for another record or with a setup element also defined in the group, a control checks that the groups have at least one company in common when the groups are different.  

In addition, a consistency check is performed for the legislations of the companies in the selected group.
At least one of these companies must have the same legislation as the one entered in the Legislation field. If  not, a warning message displays.
