Hi Allen,
Earlier there were condition types to meet requirement of taxes (JEXP - 12%, JCEP - 2%, JA1X - 1%)
Now only condition type JEXP is enough to meet the requirement. Maintain the condition record for JEXP as 12.5%. Still if any issues please do let me know the tax procedure whether it is TAXINJ or TAXINN.
Now coming to your question regarding the excise invoice type. Kindly cross check the configuration setting Logistics General -> Tax on goods movement -> India -> Business Transactions -> Outgoing excise invoices -> Maintain Default Excise groups and Series groups are maintained.
or you can change the excise invoice type manually at the time excise invoice processing.
Kindly go through the following OSS notes 2132309, 2136624.
Regards,
S.Himavanth.
