App10 UPD15 - E-Invoice India

Dear all, 

I have been working on the EInvoice solution for India following the instructions provided in IFS Apps 10 Global Extension - India Country Solution for UPD15. 
The xml I got looks like the normal EInvoice missing all the specific tags for India (e.g. INSupplyType, INGstin, INHsnCode , etc.). 

Does anyone has an idea where I miss something? 

Any advice is highly appreciated :)

Please find below some screenshots with my setup:

2. Customer

3. HSN/SAC

4. Sales Part

5. IFS Connect
