After settlement accounting has been carried out, the settled income is distributed (apportioned) among the sites involved. If settlement accounting is carried out at site level, rebate income can be distributed either by share of business volume or evenly. If settlement accounting is carried out at purchasing organization level, distribution is always by share of business volume.

In the case of even distribution, rebate income is split up among the sites in equal portions (that is, the total income is divided by the number of sites).

In the case of distribution by share in business volume, the total income is distributed among the different sites in proportion to their respective recorded business volumes (condition basis).

You can specify the desired type of distribution when you invoke the settlement accounting function. Apportionment can also cover individual months if monthly values were consolidated in the course of settlement accounting. For example, monthly business volume figures may be available even though settlement is carried out quarterly. The recording of monthly business volume figures permits the rebate income to be documented on a monthly basis. However, the extended distribution over months is carried out by share in business volume only. If business volume data exists for several article groups, purchasing organizations, purchasing groups, and months, the rebate income may be further apportioned by share in business volume.

Determination of rebate income at site level and apportionment of income can also be carried out on a customer-specific basis via the user exit LWBON003. In the process, the computation defined in the standard system is carried out in all cases. The values determined can then by modified by a customer-specific program.
