Types of Upgrade

SAP Has come up with three different types of upgrade.

This upgrade step provides you with the ability to convert many of the custom process es into standard one. Well, SAP is smarter and will ofcourse, make it more robust by adding many additional functions.
Strategic Upgrade : This is driven by enterprise SOA to provide more flexibility to business process innovation.

How does an upgrade take place?

• Basis team reviews all the steps.
• Run the SAPUP tool.
• You got to complete the modification adjustments using SPDD and SPAU.
  • what is SPDD and SPAU? SPDD Adjustments are the adjustments to the dictionary objects which had inconsistencies in it during or after the upgrade. Some SPDD adjustments have to be done inbetween the SAP Upgrades. SPAU are the adjustments carried out to the programs. What adjustments? Many times, you tend to modifiy the standard program and now the sap tries to upgrade the same program. it fails because it does not know where exactly to insert the new piece of code. Hence, these adjusments have to be done through SPAU. I forgot to mention, SPDD and SPAU are transactions.
