# Stream Set Store Variable Action

With the help of the Stream Set Store Variable Action it is possible to set a variable in the Variable Store within a stream. It is possible to define the name (key) and the value of the variable. As soon as a variable has been set, it is available in the stream itself and globally for all other streams that follow in time.
