Transformer

[pp]

I have a job where RCP is enabled thereby all columns are propagated dynamically. The column names change depending upon the data.
How can I specify a condition in the transformer by not explicitly specifying the column name that is has to operate on?

Can we specify an input column as a stage variable and then use it in the transformer?

PP, what exactly are you trying to achieve here? please be more clear.

I want to be able to use a particular field in a condition within a transformer without hardcoding the field name in the transformer.
How can I achieve this?

Thanks

pp - as far as I know this cannot be done, i.e. column names need to be used instead of positions.

I do know. It can not be done.

RCP is only ever about pass-through columns. Anything you want to derive or constrained must be named explicitly.

You might contemplate building the constraint expression as or containing a job parameter.
