Hierarchic Lists

Hierarchic lists are showing their data in tables. They are based on Based on SAP Control COLUMNTREE model. The data can be sorted hierarchically (e.g. widget Object Selection). These widget are supporting drag & drop for suitable objects. Context menu functions are available for single nodes and within the empty area.

The column layout, including the sorting and filter can be adjusted by the user. A default layout is defined in the customizing. Different functions are provided in column titles and context menus. They are described in the next topics.

General functions Search/search next and Save expanded nodes are also provided. See Tree Widgets

Search/Search next

Context menu function Search allows a text search within the loaded nodes. hits will be marked. With function Search next the next hit is marked.

Save expanded nodes

Some widgets allow saving the state of the expanded nodes. When saved, the nodes will be displayed again in their expanded state on restart.

It is not possible to save all nodes in the expanded state. Mainly available for unique structure nodes with text names.

Multi-level expansion on nodes

On expandable nodes, a context menu function is offered which allows to expand the node on multiple levels. By default, you can expand 2 levels, 3 levels, and to maximum. The availability and the maximum expansion depth depends on the widget settings.

The expansion depth is based on the node on which the function was executed. Multiple selection is possible. For specific widgets, it is possible that certain nodes are not expanded even though the maximum expansion depth has not yet been reached (for example, in recursions).

Possible Adjustments

-

Adjustment of columns

Column width as well as order can be directly changed on the screen.

Change column width

Click, hold and move the separator between two columns. The changes will affect the left columns.

Change column order

Click, hold and move the column title to move the column.

The first (hierarchic) column cannot be moved.

Show/hide columns

With context menu option Change layout on the column title columns the visibility and the sort order can be changed individually.

Optimize column width

With context menu function Optimize column width, all columns will be adjusted so title as well as context can be read completely.

Sort Options

The content of single columns can be sorted ascending or descending. A single click into the column title will initiate the sort function. A second click will reverse the sort order.

The icons left from the column title, are indicating, which columns are currently sorted. The sort order can also be configured via Context Menu Functions. Functions are also provided to remove the sorting of one specific column or to reset all table sortings.

Sort options are only available in widgets, when sorting is useful.

For some widgets a specific sort order is pre-set and not to be changed, in order to guarantee consistent display of the data. In widget Folder the folders will always be listed before the documents. Sorting is therefore limited to the object types.

Sorting multiple columns

With context menu Change layout on the column title, the sort criteria can be change for multiple columns, too.

Filter Options

Filters can be used to limit the displayed data.

Due to the multiple assignment of columns, filters are partly divided into several object types. So it is possible to filter a column only for a certain object type. For example, if a widget displays document folders and documents, the two objects share the Type column for displaying their document type.

In the filter definition, it is not the Type column that is available, but the Document Type and Folder Document Type columns. In this case, it is possible to restrict the documents to be displayed using the document type without hiding the folders.

Filter can lead to inconsistent display states in widgets. Therefore filter options are not available in all widgets.

It is not possible to filter all columns

Filters can be maintained by two ways.

Quickfilter

Filter criteria are depending on possible values in a column. One criteria can be selected and the column will be filtered accordingly. Quickfilter are not available for all columns. If a columns is multiply used, a sub menu with a selection of filter criteria appears, and the relevant criteria can be selected.

-

Enhanced filters

Context menu option Change filter starts a filter dialogue. Filters are defined in two steps:

Define the filter criteria (Move columns from the left to the right side)
Determine values for the filter criteria
