While creating the tables, sometimes we may need to update the table fields in the background. For example, if we create a table with 10 fields and in those 10 fields there are 2 fields which are User name and the Date, these 2 fields should update automatically when a record Inserted/Updated in the table. It also can be used when we want provide various validations on creating, changing or saving entries in a table.
Event Handling
When we provide event handling on table maintenance, table fields will be updated automatically when a new record inserted into the table or an existed record changes through the table maintenance generator.
To achieve the event handling in table maintenance, we need to create a table maintenance generator and then create events. Process is as follows:
Create a table maintenance generator for the table:
To create table maintenance generator go Utilities -> Table Maintenance Generator and provide following information:
Authorization Group: &NC&
Function group: Any suitable FC
Maintenance type: Two Step
Maint. screen no: Overview screen 8005
Single screen 8006
Click on Create.
Create Events for table Maintenance:
To create events on table maintenance go to Environment -> Modification -> Events -> New Entries
List of events available:
Choose maintenance event 05-Creating New Entry and provide a name of the event (This will become perform/subroutine).
Click on Editor Button to provide event handling code.
A popup will be appear, It will ask to create an include program, in which we'll write the event handling code.Click on continue.
Write the code in include for the event in the include created
