You can create and change customer content in the SAPUI5 ABAP repository. You can also
retrieve content from the SAPUI5
ABAP repository to view it.
Note Changes to content that is delivered by SAP in the
SAPUI5 ABAP repository in
customer systems are not supported. Extension concepts exist that allow custom
enhancements of content that is delivered by SAP. This depends on the type of the
content (see the documentation in question). For example, see the extensibility
information for SAP Fiori for SAP Business Suite on SAP Help Portal at
http://help.sap.com/fiori.
