Special Functions of the Hierarchical-Sequential List 

Use

The hierarchical-sequential list allows you to combine two hierarchy levels such as header and position level in a display. To do this, specify two data tables that have the same data type in at least one column. You use this column to create a relationship between the two tables.

You are able to generate a maximum of five of such foreign key relationships.

In the hierarchical-sequential list, you are able to use the following special functions.

·        Determining Data Tables for the Header- and Position Level

·        Linking Data Tables for the Header and Position Level

·        Displaying or Hiding Position Rows

You use most of the functions of the hierarchical-sequential list analog to the simple, two-dimensional table (such as aggregation, sorting, filter). Here you also have to specify for which of the hierarchy levels you want to execute the function.

Features

Linking Data Tables for the Header and Position Level

You are able to link the two internal data tables of the hierarchical-sequential list with up to five foreign-key relationships.

Methods

Function	Class	Method
Link data tables	CL_SALV_HIERSEQ_ TABLE	FACTORY (Parameter T_BINDING_LEVEL1_LEVEL2)
		SET_DATA (Parameter T_BINDING)
Get foreign key relationships	CL_SALV_HIERSEQ_ LEVEL	GET_BINDING

 

Displaying or Hiding Position Rows

By default, users cannot hide the position rows of a hierarchical-sequential list: there are no symbols to enable this function.

You are able to define a column from the header level as an expansion column. This has the following effects:

·        You are able to hide or display the position rows of a specific header row using the contents of this expansion column.

·        A symbol is displayed in each header row that the user can click to manually hide or display the associated position rows.

·        You are able to hide or display the position rows for all header rows simultaneously with your application.

Methods

Function	Class	Method
Define a column on the header level as expansion column	CL_SALV_COLUMNS_ HIERSEQ	SET_EXPAND_COLUMN
Get current expansion column		GET_EXPAND_COLUMN
Hide position rows for all header rows	CL_SALV_HIERSEQ_ LEVEL	SET_ITEMS_EXPANDED
Get current status of position rows		IS_ITEMS_EXPANDED
