Finding Payroll Results for a Specific Query
Payroll results are stored in cluster Rx of the PCL2.
The cluster key is non-mnemonic. It contains the PERNR (personnel number) and SEQNO (sequential number) fields.
The internal table RGDIR contains a directory entry for each payroll result. This entry is a sequential number (RGDIR-SEQNR) which uniquely identifies the payroll result.
Payroll results can only be imported if the payroll cluster key contains the personnel number and sequential number.
Before you can import a payroll record, you must select the entry in the RGDIR on the basis of existing data such as for-period, for-payroll area, for-payroll category, in-period, in-payroll area, in-payroll category, and so on, in order to determine the sequential number.
You will probably always have the same queries when importing payroll records. For example, "Which payroll results (original and retroactively accounted records) were written for a specific payroll run (defined by in-payroll category, in-payroll area, in-period)"?
There are standard modules that can be used. It is advantageous to use the standard modules rather than self-programmed solutions because no program modifications will be required if the payroll directory changes. The modules are described in the following section
