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.008 (Direct Debit) Nov 2016.xlsx document. These tables install with the nachaISO20022MappingDoc.zip file.
  • The ACH_ISO_Mapping_Assumptions_Table (Direct Debit).xlsx document includes implementation specifics on the mapping between ACH, to and from ISO pain.008.

Expected results

  • The ACH to ISO example maps generate an XML document which passes pain.008.001.02 XML schema validation.
  • The ISO to ACH example map generates an ACH file which passes ACH type tree validation.
