The system determines the costs per rental object or contract from the following factors:

• Measurements
• Length of occupancy
• Accumulated costs for the settlement period

The apportioning of service charges to contracts is controlled by the measurements and the length of occupancy of the rental objects. The length of occupancy is determined by contract data (rental end, notice), which takes account of the varying length of months as well as leap years.

The product of the measurement and length of occupancy within the posting period is the reference factor.

The sum of all reference factors is set against the costs, resulting in the cost factor per reference factor unit.

You determine whether, and what portion of, the calculated costs can be passed on to the tenant via the settlement participation in the contract.

If reference is made to consumption values, the length of occupancy has no significance and the apportioning is based on the recorded consumption.

The posting procedure is carried out in several steps:

1. Determination of the distribution bases according to the calculations of the participating rental objects, including an exact daily weighting depending on the measurement

All service charges of the settlement unit are credited under one credit account for each cost element and the corresponding rental objects/contracts are debited.

To do this, assign the corresponding credit accounts to the cost accounts in Customizing:

2. For service charges of the contract that can be passed on (only tenant share, no owner share and no flat rates), the receivables are posted as follows:

• For third-party usage: debit-side receivable to revenue (on contract)
• For own usage: costs on cost center to revenue (on contract)

1. Transfer down payments made

You can charge the tenant a percentage surcharge (in accordance with the incurred service charges) in addition to the service charges due. You can define this percentage rate.
