Processing the Structure (SAP Library - BC

Processing the Structure

To display or change the structure of a logical database, choose Structure from the initial screen of the Logical Database Builder, or navigate to the structure editor from another component.

Displaying the Structure

The structure editor displays the structure hierarchy. Each node is displayed as follows:

<node> is the name of the node.
<id> is the type of the node: T for a database table, S for a ABAP Dictionary type, and C for a type from a type group.
<type> is the name of the ABAP Dictionary object to which the node refers.
<text> is the short text for the node.

As usual, you can expand or collapse the subordinate tree structures, and edit individual subtrees. You can display the attributes of a node by double-clicking it. To display the structure of a node, that is, the components of its data type, place the cursor on the node and choose Display table fields.

The PUT routine function allows you to display the subroutine PUT_<node>. For this to work, the subroutine must be contained in its own include that follows a particular naming convention. For further information, refer to Editing the Database Program.

Changing the Structure

To rename an existing node, place the cursor on it and choose Edit ® Node ® Change.

To create a new node at a subordinate level to the cursor position, or on the same level, choose Edit ® Node ® Create. Nodes that you create like this in the structure editor consists at first only of its logical name, with which it is declared in the database program using the TABLES or NODES statement. To define the node fully, double-click it. You can then enter its type, the name of the data type from the ABAP Dictionary to which it refers, and its short text.

To select/deselect a sub-tree, choose Edit ® Sub-tree ® Select/deselect. To move a selected sub-tree in a structure to a position indicated by the cursor, choose Edit ® Sub-tree ® Reassign.

To delete a sub-tree, place the cursor on the node or select it and choose Edit ® Sub-tree ® Delete.
