Structure and Task of Data Field Structure PSnnnn 

Each infotype includes data fields that are only stored within that particular infotype. The fields are required when the infotype’s data structures and database tables are defined. The data fields are grouped together in structure PSnnnn to keep the definition as free of redundancy as possible. Structure PSnnnn can then be used as a substructure when further structures and tables are defined in the Data Dictionary.

Do not use the data type INT4 for the field names of structure PSnnnn .

CI Include

The Personnel Administration and Recruitment infotypes contain a customer include CI_nnnn in the structure PSnnnn . You can include your customer fields in this include. This is then an enhancement of a standard SAP infotype.

Using subtypes

If you want to divide an infotype into subtypes, you must assign structure PSnnnn a duplicate of key field Pnnnn-SUBTY in which the subtype is then stored. This field requires its own name and data element.

You must include the duplicate subtype field in the appropriate infotype screens. You can then make entries in this field.

You must also specify the name of the duplicate subtype field in the Subtype field field of table T582A when you maintain the infotype characteristics. Central infotype modules automatically write data to key field Pnnnn-SUBTY from the entries in this field. Key field Pnnnn-SUBTY does not appear on infotype screens.

A duplicate subtype field has the following advantages:
