Performing Subtype Checks
Procedure
As delivered, the system supports generic subtype checks, but cannot determine all of the applications that pertain to a particular infotype. For this reason, subtype checks are performed by means of the Business Add-In (BAdI)
HRPAD_SUBTY_CHECK
. A number of standard implementations are delivered with this BAdI, the most useful of these being implementations
CHECK_BY_T512Z
,
CHECK_BY_T531
and
CHECK_BY_T591A
. If your infotype requires subtype checks in relation to other tables, you may also create new implementations. To this end, you may refer to and copy standard implementation
CHECK_BY_T591A_CHAR1
– which checks the first character of the
Subtype
(SUBTY) field in relation to the
Subtype Characteristics
table (T591A) – then modify the copy to suit your requirements.
Caution
If foreign key checks and Business Add-In
HRPAD_SUBTY_CHECK
are simultaneously active, then the system may issue inconsistent error messages. If you do choose to perform subtype checks by means of this BAdI, it is therefore vital that you
disable foreign key checks
for your subtype fields.
