Hi Raj,
thats correct to use the GVC's.
There are no differences between MT940 and CAMT.
The business transaction codes from
8.2.6 Business Transaction Codes (GVC) from DFÜ Agreement (Appendix 3: Specification of Data Formats) are obligatory for each German Bank.
That means the business process behind GVC 109 is the same at all banks.
- 109 SEPA Direct Debit (debit; reversal debit, Core)
So all codes here have to use from all banks.
Best regards
Thomas
