Hi,
As indicated by Venkat you can use any naming convention you want.
The basic thumb rules would be for how you can ideally name them :
- Logical and be easily deciphered even if they are just appearing as codes without the text;
- Consistent across the globe if it is a global enterprise;
- Matching / Similar to Sales Org, Purchasing Org and Plants for at least two letters of the code;
- Alphanumeric Characters would be more advisable.
Have seen various ways they are addressed.
Bottom line is that, there are no real rules for this.
Hope this helps.
Thanks.
