[Report: MyCustomReport]
Title : "Hello World Report"
Form : MySimpleForm
[Form: MySimpleForm]

[#Report: Monthly Sales by Group]
   Form : SalesGroupForm
   Collection : SalesDataByMonth
[#Collection: SalesDataByMonth]
Source Collection : SalesRegister
Child Of : VoucherDate, StockGroup
Aggregation : Sum(Amount)
Compute : MonthName = Format(VoucherDate, "MMMM YYYY")

This report groups sales by stock group per month, which is impossible in standard Tally ERP 9 without TDL.

Problem: You need to track whether a sale was shipped by Air, Road, or Rail.

Solution TDL Code:

[System: UDF] Add : Voucher Type : Sales : VoucherEntry : Field : Vch_transport [Voucher Type: Sales] Set : VoucherEntryField = TransportField [Field: TransportField] Use : Field.Default Name : Vch_transport Caption : "Mode of Transport" Type : String Table : "Air", "Road", "Rail" Storage : Vch_transport_storage

[Storage: Vch_transport_storage] Persistant : Yes Type : String

Result: When you open a sales voucher in Tally ERP 9, a new dropdown appears asking for "Mode of Transport". This data gets saved with the voucher and can be printed.

You can use TDL to export data in a custom JSON/XML format for an external CRM, or import data from an Excel sheet via a TDL-driven import routine.

Writing TDL can be frustrating because Tally’s error messages are cryptic. Here’s how to stay sane: tdl for tally erp 9

Debugging Tool: Use ##SV TraceLevel = 1 in your TDL to generate a detailed log file in the Tally folder.

Problem: You want Tally to warn you (not deny, just warn) if you are selling more quantity than available stock.

Solution TDL Code:

[Voucher Type: Sales] Key : Alt+W : LowStockWarning [Function: LowStockWarning] Object : InventoryEntry Condition : $$IsRemoteCall Action : CheckStock

[Function: CheckStock] Local : CurrQty, AvailQty CurrQty = ##SVCurrentQty AvailQty = ##SVClosingBalance IF CurrQty > AvailQty THEN Alert "WARNING: Selling more than available stock. Available: " + AvailQty ENDIF

Insert this line in your TDL to see the value of a variable at runtime:

Alert "The value is: " + $$Debug:##MyVariable

Mastering TDL for Tally.ERP 9: A Comprehensive Guide to Customization

In the world of business accounting, Tally.ERP 9 has long been the gold standard for SMEs due to its simplicity and robustness. However, every business has unique workflows that a "one-size-fits-all" software cannot always accommodate. This is where TDL (Tally Definition Language) comes into play.

TDL is the application development language of Tally. It allows users to extend the capabilities of Tally.ERP 9, moving it from a standard accounting tool to a bespoke Enterprise Resource Planning (ERP) solution. What is TDL for Tally.ERP 9?

TDL is a proprietary, non-procedural, object-oriented language. Unlike traditional programming languages like C++ or Java where you define how to do something, in TDL, you define what you want. It is designed to allow developers to modify the user interface (UI), create new reports, and automate data entry without altering the core Tally engine. Why Use TDL Customization?

Customized Reports: Generate specific MIS reports, sales analytics, or stock ageing analysis that aren’t available by default.

Invoice Personalization: Design professional invoices that include company logos, specific Terms & Conditions, or industry-specific fields (like Batch No. or Warranty dates).

Data Security: Create user-level restrictions to ensure that sensitive financial data is only accessible to authorized personnel.

Automation: Automate repetitive tasks, such as auto-calculating commissions or creating "Quick Entry" screens for high-volume transactions.

Integration: Use TDL to facilitate data exchange between Tally and third-party applications like Excel, CRM software, or web portals. Core Components of TDL

To understand TDL, you need to understand its hierarchical structure. Every visual element in Tally is built using these blocks: Menu: The starting point (e.g., the Gateway of Tally). Report: The container for the entire screen. Form: The visual layout within a report. Part: A section of a form (e.g., Header, Body, Footer). Line: Individual horizontal segments within a part. Field: The actual data entry or display point. How to Install a TDL File (.tcp) in Tally.ERP 9 Every TDL file must start and end with Tags

If you have purchased or downloaded a TDL (usually ending in a .tdl or .tcp extension), here is how to activate it: Open Tally.ERP 9 and go to the Gateway of Tally. Press F12 (Configure) > Product & Features. Press F4 (Manage Local TDLs). Set "Load TDL Files on Startup" to Yes.

In the "List of TDL Files to Preload," type the file path of your TDL (e.g., C:\TallyTDL\CustomInvoice.tcp).

Save the settings. You should now see "1 TDL Loaded" at the bottom right of your screen. Common TDL Customization Examples

Digital Signature: Adding a validated digital signature directly onto PDF invoices generated from Tally.

SMS/Email Integration: Automatically sending an SMS or Email to a customer as soon as a sales voucher is saved.

Auto-Backup: A script that triggers a data backup to a cloud drive or external disk every time the company is closed.

Label Printing: Custom TDLs to print barcode labels or shipping labels directly from the Physical Stock voucher. Learning TDL: Where to Start?

For those looking to write their own code, Tally Solutions provides the Tally Developer tool. This IDE (Integrated Development Environment) offers syntax highlighting, a dictionary of Tally objects, and debugging features.

The language is highly "re-usable." You don’t have to write code from scratch; you can "Alter" existing Tally objects. For example, if you want to add a field to the Ledger Master, you simply use the #Line command to modify the existing Tally line. Conclusion

TDL for Tally.ERP 9 is the bridge between standard accounting and business excellence. Whether you are looking to save time through automation or gain deeper insights through custom reporting, TDL provides the flexibility to make Tally truly yours.

While Tally.ERP 9 has been succeeded by TallyPrime, the core logic of TDL remains largely the same, making it a valuable skill for any Tally power user or developer.
