The official currency in China is the Renminbi - RMB or CNY, it's the same.
Why do I have these two codes in the SAP? Can I delete one?
I dont want my users to use both codes for the next reasons:
Exchange rates maintainace issue.
End of month revaluation issue.
Reporting (for example customer account display - FBL5n, can sub total by currency)...etc.
