iwf_lis_agg
Creates the defined aggregate list widget of the relation and displays it on the screen.
Parameters:
[child entity [parent entity view [list]]]
- Child entity
- Name of the entity you directed the relation to. If you want to use the userexit in items of object dependent menus (e.g. in Select menus), you will not have to specify the child entity as parameter, because DataView reads the entity name from the active widget. If you want to use the userexit in items of object independent menus (e.g. in sub-menus at the top menu), you will have to specify the child entity as parameter.
- Parent entity
- Name of the entity you specified as parent entity for the relation. You can only specify entities you already related as parent entity to the child entity.
- View
- Name of the view to the parent entity of the relation. You can only specify views you already defined for relations of the calling parent entity. You can only specify a view together with the parent entity. If you do not specify a parent entity and a view, DataView creates a sub-menu with all relations you already created in your application at the child entity.
- List
- Name of the aggregate list of the relation between child and parent entity. Only specify lists containing elements of the relation table. You can only specify a list together with the view. If you do not specify a list, DataView will display the default aggregate list.
Usage as:
On_Select userexit in each menu/button-area or On_Event userexit in each state of the user interface.
