These constitute the foundational data structure in Tally. Objects (like Ledger, Voucher) contain data, and Methods are used to retrieve that data.

The TDL structural model is completely object-oriented and relies on a specific hierarchy:

The highest structural container for a specific screen view. which contain Parts

Let’s look at two real-world scenarios where TDL solves problems.

Use semicolons ( ; ) to comment your code. Documenting your logic helps when updating the code for newer Tally releases.

TDL works with pre-defined objects like Reports, Forms, Parts, Lines, and Fields. Voucher) contain data

Always use the # prefix modification symbol (e.g., [#Menu: Gateway of Tally] ) to append custom functions rather than rewriting base schemas.

[#Field: Discount Percentage] Before Load : Set as : Default : 0 Local Field : Field Discount Percent Auto Compute : If $$IsPartyRetailer Then 5 Else 10 End Auto Compute

Seamlessly connect Tally with external applications or databases.
