Derivative Rule
Alo
I’m trying to create a Source Derivative Rule that takes each inbound Stage row and produces **two** output rows. The first row should remain completely unchanged. The second row should be an exact duplicate of the first, except the **FERC** field must be replaced with the value from **A8**. I’ve confirmed that Rule Expressions cannot duplicate rows, and the `Transformer` object in Source Derivative Rules does not expose methods like `GetInputRow` or `GetSourceRecord`. I’m looking for the correct, supported API pattern for duplicating a Stage row inside a Source Derivative Rule, or confirmation that this must be done in a different rule type (e.g., Target Derivative Rule).
Any examples would be greatly appreciated
Hi ! Thank you for your response!
The duplicated record is accomplished by simply referencing the attribute that holds the dimension member (Location for example) A8#[*]
Now we are trying to copy the value of attribute A8 into the U2# dimension field for the duplicated line but we have not been able to identify the correct logical expression.
We have tried:- A8#[*]:U2#[*]=A8#[*]
- A8#[*]:U2#[*]<<A8#[*]

I believe you can use the multiply by 1 to create a duplicate record. It would be something like this:
