(<#>) Field <name> is not found
The specified field/column being referenced was not previously defined in the script.
Note: A field can reference another object, such as a PROC within a function.
In the latter case, since a reference cannot be found to the field, it assumes that it is a source or target field. Make sure that the field/column is spelled correctly, that you are using the correct datastore definition and the definition was specified earlier (i.e. before the reference is made) within the script.
