This question has been asked before
The search option (upper right of the window) can return wonderful results.
Have you tried it?

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

ESQL routines called from Mapping node are not called in a scope that has Environment as a defined correlation name.
So you'd have to do something horrendous like stick a reference in LocalEnvironment that pointed to Environment and then access that to get at Environment.
But it's a horrible horrible idea. |

Does this seem like Global Cache may be a good application here?

Is that even possible, to create a message tree element with REFERENCE data type?

Probably not. |

Dunno. Probably not. Might be able to use a SCHEMA level variable, but again it gets ugly pretty darn quick.
Again, best thing is to simply not expect to use Environment from GDM. |

So the OP is left with copying whatever interested elements from Environment to LocalEnvironment before the call to mapping node?
What's the technical challenge that makes it difficult to give mapping node access to the Environment tree natively?

And back, afterwards, yes.
