Generic Navigation Block 
A Web item that obtains data from a query view to create a generic navigation block for a Web application. This block contains keys that you can use to transfer characteristics, for example, into rows or columns.
The Web item
(Generic Navigation Block) displays the
navigational state of a query view in the Web application in the form of a
table. All characteristics and structures in the query view are listed in the
table and their filter values are displayed. You can change the navigational
status of the query view. You can transfer characteristics and structures to
an axis (rows or columns) or from an axis. You can filter according to single
values and remove the filter again.
As well as its General Attributes, the Generic Navigation Block Web item has the following attributes:
Attributes |
Description |
Read mode (BOOKED_VALUES) (BOOKED_VALUES_N) “Master data table” “Dimension table” “Posted values” |
This attribute specifies which values in the master data table are copied to the Checkboxes Web item as filter values: · M: All values from the master data table. In some circumstances values that do not appear in the data provider under the current filter conditions and that produce the result No suitable data found when filtered, might also be displayed. However, this process is fastest under certain conditions. · D: Values that are basically posted, whereby the current drilldown status is not fully taken into consideration. · Q: Only values that are also posted in the data provider under the currently valid filter conditions are displayed. It can take a long time under certain circumstances. Read mode for filter items The “master data” read mode may lead to many unposted values being displayed; the “posted values” read mode may be slow. |
Grouping axes (SHOW_AXES_GROUPING) ‘X’ = Yes, ‘ ’ = No |
If you set the indicator for this attribute, free characteristics, characteristics in the rows and the characteristics in the columns will be displayed in groups. |
Characteristics of the rows collapsed (ROWS_CLOSED) ‘X’ = Yes, ‘ ’ = No |
If you set the indicator for this attribute, the characteristics for the rows are displayed collapsed in the grouped display. |
Characteristics of the columns collapsed (COLUMNS_CLOSED) ‘X’ = Yes, ‘ ’ = No |
If you set the indicator for this attribute, the characteristics for the columns are displayed collapsed in the grouped display. |

Order entries next to one another (HORIZONTAL_ALIGNMENT) ‘X’ = Yes, ‘ ’ = No |
As well as arranging the characteristics below one another, you can also display them next to one another. In many cases, this makes better use of the display area and there is a stronger visual link between, for example, the table and the navigation block. |
Entries next to one another (HORIZONTAL_NUMBER) Default value: 3 |
Describes the maximum number of characteristics that can be displayed next to one another. If the navigation block contains more than the specified number of characteristics, then it is automatically displayed in more than one row, where the number of characteristics per row is optimized regarding the equal distribution of rows and the required number of characteristics.
This attribute is only included when HORITONTAL_ALIGNMENT (Define entries next to one another) is activated. |
Maximum filter value length (FILTER_VALUE_LENGTH) Default value: 80 |
You specify the number of characters, according to which filter value is indicated, by <Number>.
If you set the value to 0, then the complete filter value is displayed. |

You can display input help in a different frame from the data. If you activate this attribute, input help is displayed in the same window.
This parameter is not offered in the Web Application Designer and can only be used for parameterization in the Web template. |
List of characteristics with read mode (IOBJNM_LIST) |
This attribute contains a list of characteristics with read mode. You can select a characteristic of a structure and activate the read mode for it. |
Affected data provider (TARGET_DATA_PROVIDER) |
This attribute contains a list of all data providers to which the navigation block is sent.
If you filter according to a characteristic and then activate this attribute, the different data providers for the Web item are notified. For further information about this attribute, see General Attributes. |
Table interface class (MODIFY_CLASS) |
Table interface class By using the Web design API for tables, you can adjust the cell content individually in the navigation block. See also: |
List of navigation block entries (ITEM_NAV_BLOCK_IOBJNM_N) (optional)
In the WAD, this attribute is displayed using the List of Characteristics with Read Mode attribute (IOBJNM_LIST). |
