I have quite a large job to do for SAP and I asked for terminology. They used to sell a CD but now they just say look at https://help.sap.com - which is fine but SAP do not link their English and German pages, although they are frequently available in pairs.

Eventually, I found that:

1. if you click on Kim's magical SAP link and replace XXX in the box at the top of the page with the German term you are looking for, you will be offered a choice of SAP help pages.
2. Open the one that looks promising and you will find German text which helps you to understand what they are talking about.
3. If you find DE in the address shown by your browser and replace it with EN, you will usually (not always) be shown an SAP-approved translation.

Groovy huh? I asked the SAP support person if they couldn't spend 5 minutes to add an automatic link, I got the "I am so sorry" response. SAP employ 55,765 FTEs (that's people to you and me). arf, arf, arf, arf, arf. Anyway hope this helps a bit.

Update!
In the meantime, some of the pages now have a language select box, which makes life a little easier. Unfortunately the search logic on the SAP site restricts the results to the language currently selected, so you have to remember to change the language back to German before you look for anything else. Google's search is smarter and finds more hits.
