Assumptions

The ACH Returns to ISO 20022 transformation example maps enforce pre-conversion rules.

The following are assumed if no rules are violated:
  • The maps proceed to the transformation phase.
  • Mapping is based on the NACHA ISO 20022 Tool for camt.053 (returns) Nov 2016.xlsx document.

The ACH_ISO_Mapping_Assumptions_Table (Returns).xlsx table includes implementation specifics on the mapping between ACH and ISO camt.053.

Expected results

  • The ACH Returns to ISO 20022 example maps generate an XML document that passes camt.053.001.02 XML schema validation.
  • The ISO to ACH example maps generate an ACH file that passes ACH schema validation.
