Why would this produce an error within my compute node:
| Code: |
CREATE FIELD Environment.Variables.Derived_Data.My_Data.My_Group;
DECLARE My_Group_Ref REFERENCE TO Environment.Variables.Derived_Data.My_Data.My_Group;
|
It is point at the following:
| Code: |
SET My_Group_Ref[b]{error right here}[/b][LOOP_CNT].Sales_Individual_Production_Number = "InputBody"."PDCR"."PRODUCER_NUMBER";
|
I don't see the problem because I have similar code above this one that is not creating an error. |

The error I am getting is the following which now does make sense, but I would like a little clarification on how you would do this in a loop and still use a REFERENCE TO.
| Code: |
BIP2916E: (277, 6) : Correlation names cannot be qualified.
Correlation names (the first name in a field reference) must be a simple name identifier. They cannot be qualified by a type, an index, a list specifier ([ ]) nor may the name be calculated by an expression.
Ensure that all correlation names are unqualified.

| The Error itself saying that you can't use list operator with correlation names.because My_Group_Ref is a correlation name use can't use a list operator with that. |

Okay, suppose you have a set of MyGroup elements - MyGroup[1],MyGroup[2], etc..
When you create a reference to just MyGroup, you are creating a reference to MyGroup[1]. So, you can't then use MyGroupRef[2] to refer to MyGroup[2], since that is pointing to the second child of MyGroup[1].
If you created a reference to MyData, then you could use MyDataRef[1] to point to MyData.MyGroup[1], and MyDataRef[2] to point to MyData.MyGroup[2].
