In the rush to get to SAP’s HANA database, some customers have not given proper consideration to the Z-code that has been developed over the years and its compatibility with the new DB. During the initial SAP implementation, nearly every company that I know of was “special” in some way and choose not to go with the SAP standard. Therefore, we all have substantial Z-code we used to fill that and other gaps in our processes. Now with the HANA DB on the scene, some are finding that post migration, some of their Z-code either won’t work or has some serious performance issues running on the HANA database.
