Application Exit via AppCC BAdI
For every Application Configuration Controller (AppCC) component configuration you can create an associated Business Add-In (BAdI) implementation. The filter key for the BAdI is the AppCC component configuration name. The implementation informs the configurator what the generic key is going to be and how it has to be interpreted.
Features
The BADI interface IF_HRESS_EX_PER_CONFIG_KEY contains the following methods:
READ_TEXT_FOR_IMPLE
This method returns the text that the configurator displays for generic key.
GET_CONFIG_KEY
This method returns the appropriate key value for a particular PERNR.
For more information, see BAdI documentation.
