  • If you have changed master data, you have to execute the change run. By reading the master data, the active version is read. If this is not avalaible, an error is raised.
  • If an attribute is time dependent, you also have to define when it should be read: at the current (system date), at the beginning or end of a period (defined by a time characteristic of the InfoSource), or at a constant date that you enter dirtectly. System date is used as the default
  • If an attribute is time dependent, you also have to define when it should be read: at the current (system date), at the beginning or end of a period (defined by a time characteristic of the InfoSource), or at a constant date that you enter dirtectly. End of a period date is used as the default
  • If an attribute is time dependent, you also have to define when it should be read: at the current (system date), at the beginning or end of a period (defined by a time characteristic of the InfoSource), or at a constant date that you enter dirtectly. A constant date is used as the default

Frage 29

Frage
