As well as the type of updating required, you can also define the period unit.

The period unit defines the time level at which the statistical data is to be cumulated. You can select the following period units:

• Day

• Week

• Month

• Posting period (with business year variants if necessary)

You can define the period unit for updating for each information structure that is supplied in the standard system.

The following table gives you an overview of the period units used for updating those information structures of the Retail Information System that are supplied as standard.

Information structures S079, S082, S085 and S107 always have the same period unit as the corresponding information structure containing the movement data. If the period unit for the information structure containing the movement data changes, the period unit of the information structures named above will also change.

No data is written to information structures S117 and S119 either. These information structures are supplied with data from S120 using Copy Management. The period unit for these information structures is Day.
