In payroll, the original records for the processing of absences are first imported from the Absences infotype (2001), and stored in payroll table AB by function RAB. During this process, the relevant valuation rule is assigned to each absence record according to the Valuation of absences table (T554C). The valuation rules are used valuate the absences in function PAB.
Before absences are valuated, table AB often has to be split to take account of business regulations, such as the end of the period of continued pay.
In this step, you set up this refinement. In the Coverage History table, a flag is stored for each absence day, which indicates the type of valuation for that day. The information in the Coverage History table is used by function XNAB to refine table AB further.
Function XNAB must be included in your payroll schema.
The flags that have to be set in the Coverage
History table for the specified conditions, and the information on which
valuation rule is to be used to represent the valuation rule from the Coverage
History tab le, with the appropriate flags, are stored in country-specific or
industry-specific tables.
If no such tables exist for your country or industry, you can use the SAP
enhancement HRPTIMAB Refine absences to implement the same
logic.
