In order to allow daytime to be displayed in the browser, usually several browser lists are required. They must be explicitly created. It is recommended to copy and customize default lists. Default lists themselves should not be used as browser lists, because DataView uses them internally and, thus, they should not be changed. The customizing of browser lists can be limited to the functionality required for the browser, because they are not intended to be displayed on the desktop. They are automatically virtually opened or closed both after calling iwf_brw_ent and during navigation in the browser, respectively.
The following picture uses the Dataview relation Item-Provider of the meditronic data model to show, which browser lists you have to create, in order to display the providers for an item.
As you can see, a parallel structure of lists with several browser lists must be created to display a structure with several levels. The root of the structure is the first browser list passed in the browser call. Any additional level results, if an iwf_lis_...-function for calling another browser list is installed in the Select menu of the browser list(e.g. iwf_lis_ref, iwf_lis_agg, iwf_lis_cns, iwf_lis_uni or individual user exceeds with the name iwf_lis_xxx). You can use several iwf_lis_...- calls in the Select menu to display several relations to the parent element within one level (e.g. all documents referring to the item in addition to the supplier).
