Dataset Modeler (ttrpidatasetm)

Use this session to to specify and maintain datasets based on the LN data model. These datasets are executable and repeatable with different parameter settings and usable as input for configuring GenAI prompts.

In the Datasets (ttrpi5100m000) session, click New to initiate a new dataset configuration and start the Dataset Configuration screen.

In the Dataset Configuration screen, configure these fields:

Field Description
Dataset Name Specify a unique name. The name can contain only lowercase letters, numbers, dots, or underscores, and must start with a letter or a number.
Description Additional information about the dataset.
Main table Select an LN table that corresponds to the main table of the target business session.
Selection Index Select an index from the list of indices associated with the selected main table. The selection index must correspond to the current view of the target business session.
Use Camel Case Select this check box to use descriptive names instead of technical names for tables and fields. The field descriptions are applied to the dataset field descriptions using Camel Case. Any manual changes are overwritten when you toggle this option.
Collection Name PostFix Specify an optional postfix for the collection name. A collection represents the complete set of selected records and corresponds to the node directly below the root node in the XML structure.
Row Name PostFix

Specify an optional postfix for the collection row name. A row represents a single record from the selected record set and is repeated within the collection node in the XML structure.

After providing all the required information and clicking OK, the screen closes and the Data Modeler opens. The Data Modeler includes these configuration panels:

  • Tables
  • Fields
  • Properties
  • Selected Fields

When you open an existing dataset in the Datasets (ttrpi5100m000) session, this view opens directly and the Dataset Configuration screen is skipped. To open the Dataset Configuration screen, click Dataset Configuration on the main toolbar.

Tables

This panel displays a tree structure of references for the main table.

Refers to
Lists the tables that the main table references.
Referred by
Lists the tables that reference the main table.

Fields

This panel displays the fields of the currently selected table. The selected table can be the main table, a Refers to table, or a Referred by table.

These columns are displayed:

Column Description
Selected Indicates whether the field is selected for use in the dataset.
Field The field code.
Element The element of the field.
Description The field description.
External Name The name by which the field is recognized in external systems. This name is editable. Depending on the Use Camel Case setting, the name is either the camel cased description or the technical name in the format {tablecode.fieldcode}.
Note: Any manual changes are lost when you toggle the Use Camel Case option in the Dataset Configuration.

Properties

This panel displays these properties:

Properties Description
Table Name The name of the selected table.
Ordering Index Lists all indexes of the selected table. By default, the Selection Index specified in the Dataset Configuration screen is used.

The dataset output is ordered based on the selected index.
Filter Present Indicates whether filters have been configured for the selected table. Click this button to start the Dataset Filter (ttadv9140m000) session.
Collection Name The XML node name that represents a collection of related records. By default, this is the table name, but it can be edited. During execution, the collection name postfix is appended, if specified.
Row Name The XML node name for each record. By default, this is the table name, but it can be edited. During execution, the row name postfix is appended, if specified.

Selected Fields

This panel displays a tree structure of all fields selected for inclusion in the dataset.

Selected fields can be reordered by using drag-and-drop.
