Now Tally customization is so easy
Tally, the flagship product (which started as a simple bookkeeping system, 20 years ago), is today a comprehensive, integrated solution – covering several business aspects of an enterprise. These include Accounting, Finance Management, Receivables/Payables, Inventory Accounting, Inventory Management, BoM-based manufacturing inventory, multi-location/multi-currency/multi- unit handling, Budgets and Controls, Cost and Profit Centres, Job Costing, POS, Group Company consolidations, Statutory Taxes (Excise, VAT, CST, TDS, TCS, FBT, GST etc), Payroll Accounting, and other major and minor capabilities. It has served as an ERP and Tally Prime for small enterprises over the past 16 years.
Tally Definition Language is the application development language of Tally. TDL has been developed to provide the user with the flexibility and power to extend the default capabilities of Tally, and integrate them with the external applications. TDL provides a development platform for the user. The entire User Interface of Tally.ERP 9 and Tally Prime is built using TDL. TDL as a language, provides capabilities for Rapid Development, Rendering, Data Management and Integration.
Any Tally.ERP 9 or Tally Prime user can learn TDL and develop extensions for Tally.
A definition language provides the users with ‘Definitions’ that can be used to specify the task to be performed. The user can specify the task to be performed, but has no control over the sequence of events that occur while performing the specified task. The sequence of events is implicit to the language and cannot be changed by the user. TDL works on Named Definitions, which means that every definition should have a name and that name should be unique. TDL has User Interface Objects like Reports, Forms, Parts, Lines and Fields as definitions.
TDL can define Reports, Menus, Forms, and so on, but the Definitions will not have any relevance unless they are used. Definitions are deployed by use, not by existence.
TDL is based on concepts pertaining to Object Oriented Programming. This language has been created for reusability. Once a definition is created, it can be reused any number of times. Besides the reusing capability, the user can also add new features, along with the existing definitions.
Tally.ERP 9 and Tally Prime has a singular view of all the TDL Definitions, which means that the Tally.ERP 9 or Tally Prime executable reads TDL (user defined and default) as one program. On invoking Tally, all the default TDL files of TDLServer.DLL will be loaded. The user TDLs will be subsequently loaded as specified in Tally.ini.
TDL is a language based on definitions. It is possible to reuse the existing definitions and deploy them. This is a language meant for rapid development. It is possible to develop complex reports within minutes. The user can extend the default functionalities of the product by writing a code consisting of a few lines.
Multiple Output Capability
The same language can be used to send the output to multiple output devices and formats. Whenever an output is generated, it can be displayed on the screen, printed, transferred to a file in particular format, and finally mailed or transferred to a web-page using Http protocol. All this is made possible just by writing a single line of code. Just imagine the technology used to develop the platform that such a complex task is developed and implemented using only a few lines.
Data Management Capability
As discussed earlier, the data is stored and retrieved as objects. There are a few internal objects predefined by the platform. Using TDL, it is possible to create and manipulate information on these with ease. Suppose, an additional field is required by the user to store information as a part of the predefined object. This capability is also provided in TDL, i.e., by using TDL, the user can create a new field and store a value into it, which can be persisted in the Tally.ERP 9 and Tally Prime database.
To meet the challenges of the business environment, it becomes absolutely mandatory to share information seamlessly across applications. Integration becomes a crucial factor in avoiding the duplication of data entry. The Tally.ERP 9 and Tally Prime platform has a built-in capability of integrating data with other applications. The following are the different types of integrations possible in Tally.ERP 9 and in Tally Prime:
● Tally to Tally using Sync
● Tally to external applications in various data formats
● External DB to Tally using XML and SDF formats
● Tally DB to external applications using ODBC
● External DB to Tally using ODBC
