SAP Upgrade Types

SAP has three main types of upgrade.

Technical Upgrade: Considered to be the fastest upgrade which does not disturb any of the existing business processes.

Functional Upgrade: This upgrade starts with a technical upgrade, mentioned above. A functional upgrade allows new functionality to be implemented as part of the upgrade project. This upgrade type also provides you with the ability to convert many of the custom process into standard functionality.

Strategic Upgrade: This is driven by enterprise SOA to provide more flexibility to business process innovation.

How to Upgrade SAP Obsolete Functions

What are SAP obsolete functions?
Standard SAP function modules are frequently used by SAP customers for implementing unique functional requirements within their organization. As SAP releases new versions of its ERP such as ECC 6.0, previous versions of function modules are retired from SAP's code base. SAP does so by declaring the old function modules as obsolete. 

An example of this is that SAP declares function modules obsolete if they don't support Unicode. If your company undergoes a Unicode conversion then these function modules will require replacements; otherwise you will encounter a definite runtime error.

Conclusion: The SAP Upgrade as a Competitive Weapon

While the tendency is to view upgrades as a necessary evil in the enterprise software market, the reality is that upgrades can be an important part of a company's overall competitive profile. This happens ideally in the case of a functional upgrade, though it can also be the case with a technical upgrade that unleashes a capability, such as Unicode support, that in turn helps open up new markets and opportunities.

The Nine Best Practices for SAP Upgrade Success

While a solution like Panaya can greatly streamline the overall upgrade process, a good tool by itself will rarely have the desired impact unless an accompanying set of best practices are implemented alongside the tool. Indeed, implementation failure generally takes place in the absence of any direct technical problem with the software. In virtually every case of implementation failure that EAC has analyzed, the failure could be traced directly to the people in charge - be they in the internal IT department, or employed by an outside systems integrator - and to the processes and best practices they either implemented poorly or failed to implement at all.
