I'm not sure where to ask this question. I'm trying to find out the legal values for a SAP LANG data type. This is a single-character key for a language (e.g. 'E' for English). Specifically, I'd like to know the keys for German, French, and Japanese. My guess would be 'D', 'F', and 'J', but I'd like another opinion. The SAP data element I was looking at is RSPOPALANG, but when I dig down into it in the dictionary I don't find an enumerated value range.
