PERIODISCH - Notes on Required Periodic Procedures

To ensure productive operation, you also have to schedule technically required programs in addition to the periodically scheduled programs necessary for business, such as debit position, dunning and the payment program. To ensure system performance, we recommend that you run the following programs as background jobs:

1. Programs for cash flow update:
   
   RFVICF00 for rental agreements and RFVICN70 for general contracts
   
   Background:
   The cash flow for the rental agreements and the general contracts are generated in advance for a certain period of time. It contains the planned records for the periodically recurring postings. A parameter in Customizing determines how far in advance the cash flow is generated (usually two years). The cash flow must be regularly updated further into the future so that the periodic postings can be carried out correctly after the period is over. SAP recommends that you schedule the above-named programs six months prior to the debit position.
2. The program to update of the status from the occupancy status of the rental unit:
   
   RFVIBL00
   
   Background:
   The rental unit status is determined in two ways:
1. By the occupancy type (occupancy history), in which data indicating whether a rental unit is/was/will be used by a third party, for own use or vacant is updated time-dependently
2. By the system status, which is not time-dependent and which represents the current status of the object. The system status controls which business processes are allowed or not allowed for a rental unit.
   

Certain changes to rental agreements (such as notice given, changes to rental start and end dates, conclusion of a new rental agreement, etc.) affect the occupancy history of the rental unit.

If this change is already valid on the day the change is made, for example the conclusion of a rental agreement starting on the current date, the corresponding status (system status which controls allowed business processes) of the rental unit is immediately updated.

If the change is to take place in the future, the system schedules the system status update for the corresponding date by updating the occupancy history for the future.

The system status can only be updated on the day that the change (such as rental start date for new agreement) becomes valid. To do this, the report RFVIBL00 reads the occupancy type for the current date and uses this information to update the system status of the rental unit.

SAP therefore recommends that report RFVIBL00 be scheduled daily sometime between midnight and the beginning of your business day.
