SAP Upgrade to latest SAP release
The SAP ECC system was on a significantly older patch version. It was important that the SAP ECC landscape and the SAP kernels be upgraded to the latest available versions to provide stability, enhanced functionality and performance improvements.
SAP has interfaces with other systems. We had to test the full business cycle in connected systems to ensure that the business data was transacting correctly between SAP and other systems.
Customizations related to Mexico Electronic Invoice are country specific enhancements. There were issues related to cryptographic libraries and Z developments which had to be resolved.
The time available for acceptance testing was short (4 hours). The key business users had to conduct testing of all important scenarios to approve the upgraded SAP system.
The upgrade plan was shared with the business regarding production downtime, acceptance testing and Go-NoGo criteria.
On the designated maintenance window, the SAP Production was upgraded by our SAP BASIS team.
