EXIT_SAPLNVVN_001 - IS-H: Guarantor Maintenance Enhancement

PERFORM Short Reference   CL_GUI_FRONTEND_SERVICES - Frontend Services  
This documentation is copyright by SAP AG.

Functionality

With this function module you can intervene in the processing of guarantors (for transactions, see documentation on SS_TCODE). It is called in the overview screen for the processing of guarantors. The call is performed at the event PROCESS AFTER INPUT just before the module for handling the function input is executed (module OK-CODE). It is primarily intended for the implementation of additional plausibility checks. However, you can also modify the function input so as to call your own functions within the processing of guarantors.

Example

You want to check whether an account balance is specified for each guarantor on the overview screen. The account balance is located in the field BALAN in the table SS_TNVVN. If you want to issue an error message, proceed as follows:
SET CURSOR FIELD 'DYNP-BALAN' LINE n.
MESSAGE S... WITH ...
SS_OKCODE = 'TEST'.

Notes

Please make sure you don't execute any runtime-intensive functions, since this is a dialog function. Moreover, you should NOT use any statements which prevent the return to the point where this function module was called (e.e. LEAVE SCREEN, LEAVE TO TRANSACTION).
