I have mapped 3 columns to Output signature :
THKFISNO : AGGREGATE.THKFISNO
At the mapping, I am drag-dropping the reusable mapping and it brings input-output signatures.
I am passing STG1_ABONE.ABONEUN to input_signature to use this column to group by.
At the target mapping, I am getting bill amount and bill details and also payment details.
Reusable component has subselect option, but as I understand it is not working with input signature, but works with only output signature.
Reusable mapping has no physical diagram and the scenario can not be produced. It could be better to have an option to generate a stage table for only output signatured reusable mappings like yellow interface at ODI 11g.
