Seasons will be empty before any seasons has been mapped, or uploaded* in a master data file (PRICAT).
Suppliers must map a season “Name” to a universal “B24 Season” before a master data file (PRICAT) can be uploaded. This "Name" must be the same as for "Period/Season" in the header of the master data file (PRICAT) to be uploaded.
If using any of the "B24 Season" in the master data file (PRICAT), there is no need for mapping it before uploading. The season will be mapped automatically.
Buyers don't have to map seasons, unless they want to receive other season names than the universal seasons, "B24 Season". Universal seasons, "B24 Season", will automatically be added as a new season on the buyers side with the universal seasons, "B24 Season" as "Name".
