Storing Data in PCLn Files

Data from the different HR application areas is stored in data clusters in PCLn files (n = 1, 2, 3, or 4).

This collection of data objects can consist of:

The structure of the PCLn files provides a framework for the individual application areas.

Each application area must have a two-character cluster name (relation ID). It must also have a key structure; 40 bytes of the SRTFD field are available for this structure.

When a record is exported to the PCLn file, the cluster ID is written to the RELID field and the key value to the SRTFD field.

Naming convention for includes when defining clusters:

RPCnxxy0 n = 1, 2, 3 or 4 (for PCL1, PCL2, PCL3, PCL4)

xx = cluster ID

y = country indicator

Description of Cluster Data using Cluster RX as an Example

The data definition is stored in the include RPC2RX00 in accordance with the above naming conventions.

Structure of cluster key:

  Data:  BEGIN OF RX-KEY.

           INCLUDE STRUCTURE PC200.

         DATA: END OF RX-KEY.

The DDIC structure PC200 contains the fields PERNR (personnel number) and SEQNO (sequential number).

The data definition of the cluster also contains other internal tables.

For a list of available data clusters, refer to the domain description in the Data Dictionary.
