2468616 - Mexico Localization: FAQ for A29 DIOT Report



HOT TOPIC: This report is still maintained and support for releases prior to S/4HANA 1709. For releases 1709 and above, it was replaced by the ACR Mexico solution. See SAP Note 2986139 for more details about ACR Mexico for VAT declaration.


This SAP KBA aims to provide a complete list of SAP Notes to be implemented for Mexico's A29 DIOT report solution (also known as Monthly VAT Return for Vendors) and clarify questions about the use and customizing of it.

DIOT is 'Declaración Informativa de Operaciones con Terceros' and A29 is the name of the legal requirement from SAT (national tax authority from Mexico).

We intend to maintain this SAP KBA updated with new SAP Notes and other future changes regarding this topic, based in the general resolutions from SAT.

We also invite you to check out the SAP KBA 2525257, in order to keep updated on overall Localization Latin America topics and solutions.
