Completely new requirements due to increased complexity

So far, views did not play an important role in the SAP context no monitoring available

For CDS views are essential

crucial to have a possibility to monitor CDS statements, which means the views / functions,

especially with regards to their dependencies

So far, static SQL was not common in the SAP context no monitoring available

With ZDO this changed (~thousands of procedures & triggers for ZDO)

Two detail views to provide information about them, their create statements, and their dependencies…

With CDS this changed (new need to monitor the CDS functions)

Core Data Services (CDS) & Zero Downtime Optimization (ZDO)


Dependency Browser

Possibility to browse the dependencies of

“Views”

“Table Functions”

“Scalar Functions”

“Tables”

“Procedures”

“Global Variables”
