The error “INVALID_KEY_OR_REF” occured when trying to install India localization suitetax engine.
The possible reason for the error is that the nexus “India” is not created in that NetSuite account. The account should have the country as “India”.
To create nexus:
- Go to Setup> Company> Countries.
- Create the country “India”.
- Go to setup> Accounting> Nexus.
- Create a new nexus “India”.
