## Checking the Standard Manipulation Functions

Standard manipulation functions are basic functions which are applied to create, change, delete records etc. Whenever one of these functions is executed (e.g. iwf_del_lis) certain mask events are verified. The verification of the user's access privilege to modify a record is performed immediately before the corresponding mask event is processed (e.g. edit action, pre-action userexit) and is therefore consistent for all access paths of this function.

This check is activated by means of an entry in the Privileges checked in Forms mask. To open this mask, select the Manager > Permissions > Role Model > Privileges checked in Forms menu option. This list provides definition functions for the definition of checks for the current entity (or the current type or relationship).
