TDL Enhancements in Release 6.2

With Release 6.2, Tally.ERP 9 directly generates GSTR-1 and GSTR-2 in JSON format which is the accepted format in the GST portal. In TDL, we have enhanced some of the integration capabilities to support the export and import using JSON format.

Export

Report-based export in JSON format using the attribute JSON Tag at UI definition level.

o A new attribute JSON Tag is introduced at UI definition level from Form to field to specify the tag name in the exported file.

o A new attribute Plain JSON is introduced at report level to ensure whether it should export formatted JSON or not.

Productivity suite-based JSON export using the attribute Resource Type at Resource level and JSON Map attribute at Form level.

o The form attribute Map is enhanced to support JSON mapping at form level.

o The attribute Resource Type is enhanced to support JSON.

Import

File-based Import using File JSON as a Data Source in collection.

o The collection attribute Data Source is enhanced to support reading from JSON files. You can populate all the data from JSON file to a collection using the data source type File JSON .

o A collection attribute JSON Object Path is added to read a specific data fragment from the given JSON file and gather collection based on it.

o A collection attribute JSON Object is introduced to specify the object (user-defined or schema object) name to map with data from a JSON file.
