Creating a TTX file in Crystal Report

TTX file defines the fields. The names of these fields should be the same as of the names of the Properties that user wants to display in the report. The name of the TTX file should be the same as of the name of Class. One TTX file defines for one Class only. For example, If you want to show all the Equipments. One TTX file named EQUIPMENT.ttx should be defined. If you create TTX file named EQUIPMENT, then this template works for all the classes that are derived from EQUIPMENT like PUMP, VESSEL etc. But if you define PUMP.ttx, it will not work for EQUIPMENT class i.e. it supports the polymorphic behavior.
The table name (Or name of TTX file) should be the same

Defining TTX and Linking Related Tables

• These 2 tables in crystal report need to be linked together to show related data correctly.

• Link these 2 tables in Database Expert dialog. Select Database -> Database Expert menu item.

• Press Clear Links button.
• Create a new link between instanceID fields (from PIPING_NETWORK_SYSTEM to PIPING_NETWORK_SEGMENT) of both tables using drag and drop.
• Double Click on the link to edit it and select appropriate options.

• Click OK in Link Options and Database Expert dialog.
• A warning message may appear. Ignore it.

Creating Group
