Hi Harshal,

What is model mapping for ZW GST Export Invoices format (IN)?

You need to create a new derived version of model mapping and add mapping for Model/TaxInvoice/Patner/Email that can return data with correct binding.

Then you can activate "Default model mapping" for the derived model mapping and run the report.

Hi Alireza,

Thanks for your reply. I am attaching the versions. Please have a look and let me know. Should all the config have the same versions?

Hi Harshal,

It seem that you have used derived version of GST INVOICE FORMAT (IN). Ref. to the error message, it seems that there is not a biding for File/Root/BuyerDtl/BuyerDtlVal/Em. It can be related to the model mapping that there is not correct mapping on TaxInvoice.Partner.Email.

If the model mapping is created correctly and it will fetch data, please check if the model that you use in format designer has the same version as the model mapping. It means that you use the recent version of model mapping that the binding exists.
