Assumptions

The example maps enforce the pre-conversion rules and, given that no rules are violated, the maps proceed to the transformation phase.

Mapping is done based on the NACHA ISO 20022 Tool for pain.001 (credit transfer) Nov 2016.xlsx document.

The ACH_ISO_Mapping_Assumptions_Table (Credit Transfer).xlsx includes some implementation specifics about mapping to and from ACH and ISO pain.001.001.03.

These tables are installed with the nachaISO20022MappingDoc.zip file.

Expected results

• The ACH to ISO example maps generate an XML document that passes pain.001.001.03 XML schema validation.
• The ISO to ACH example maps generate an ACH file that passes ACH type tree validation.
