Electronic Accounting for Mexico using UUID field
As per new rules in Mexico, the electronic number of size 36 chars generated by Govt Invoicing system should be stored in SAP accounting document for every invoice generated and issued to customer. We need to implement this and at the same time heard SAP Mexico would also provide a solution where this data can be stored in a unique field called UUID, may be through a note.
Has anyone implemented this legal change and if so how and what are the ways to retrieve this data and challenges around it. There are some discussions on SCN however they are in Spanish, so couldnt follow in full.
