Title: Use Case - Posting from SAP back-end
### Environments
### ESME Users
### Bot Details
The bot uses the Apache ESME [API](http://cwiki.apache.org/confluence/display/ESME/API+2.0+-+Design)
to receive messages that are addressed to it. The bot then provide
some basic filtering to determine what is required. For example, messages
that are tagged with the word "PO" would get information about purchase
orders. Messages tagged with "mat" would ask about materials.
There are various options for the bot to communicate with the back-end.
These options are primarily based on what programming langauge is being
used, the platform, etc.
