For a IFS9 customer we have created a makeshift solution to create Cambodian invoices in Excel, where the names etc in Khmer are stored in Excel tables and found using lookups, or as hardcoded prompts. I guess Oracle supported Khmer, but IFS not - so that was the solution.

How is Khmer support with the Cloud version?

We do not actually need the language installed as such with translations etc, but be able to enter various names and descriptions in Khmer. I take it for granted(?) that custom report layouts handle Khmer just like eg. Arabic.
