Assumptions

  • The example maps enforce the pre-conversion rules and if no rules are violated, the maps proceed to the transformation phase.
  • Mapping is done based on the NACHA ISO 20022 Tool for pain.002 (reject) Nov 2016.xlsx document.
  • The ACH_ISO_Mapping_Assumptions_Table (Reject).xlsx includes implementation specifics on the mapping to and from ACH and ISO pain.002.

Expected results

  • The ACH to ISO example maps generate an XML document which passes pain.002.001.03 XML schema validation
  • The ISO to ACH example maps generate an ACH file which passes ACH type tree validation.
