Structure mapping

Hi,

I'm using AIF to process IDOC sent in ECC from PI. My scope is to calculate some value wtih Idoc fields.

I have generated dictionary structure for the Basic Type with transaction /AIF/IDOC_GEN. In customizing I defined interface with the same value for fields SAP and RAW data structure. In the "Define Structure Mappings".

In this case I can use the Mapping only al the root level, if I use mapping on the others level it doesn't works.

It's possible to use mapping if the interface have the same structure in SAP e RAW?

Thanks
