Is there a reason that this works:

Quote:

IF InputRoot.MQMD.SourceQueue = 'XYZ' THEN
SET Qualifier = 'XMLNSC';
ELSE SET Qualifier = 'JSON.Data';
END IF;
SET OutputRoot.{Qualifier}.Base.XYZ ='1';

but this doesn't

Quote:

IF InputRoot.MQMD.SourceQueue = 'XYZ' THEN
SET Qualifier = 'Environment.Input';
ELSE SET Qualifier = 'InputRoot.JSON.Data';
END IF;
IF {Qualifier}.Base.XYZ ='1' THEN
SET A = 'A';
END IF;

I want to set the 'top level' of a reference to either

Quote:

Environment.Input

Quote:

InputRoot.JSON.Data

depending on whence a message comes

Sorry - I should have been more specific:

The failure case gives me an error when I save the ESQL file.

The Problem description in the Toolkit for the line

Code:

IF {Qualifier}.Base.XYZ ='1' THEN

is as follows:
