The purpose of this function is to allow the user to erase ALL entries from the MENU database for the selected subsystem. This differs from a DELETE which may be halted if there are any restricted links on any related tables. An ERASE will ignore any restrictions and cascade the delete down to the bottom of the relationship hierarchy. It would be wise to perform an export of the details first so that any mistakes can be recovered.
This form is accessed by selecting entries in the List Subsystem screen before pressing the 'ERASE' button in the navigation bar.
For a complete description of how this type of form works please see Transaction Pattern ERASE 1.
