In Our Dev System We Have Opened The Client With All Options ``changed Without Automatic Rec,`` ``changes To Repository And Cross Customization Allowed,`` And ``protection Level-0 No Restriction`` In Scc4. The Developers Complain That They Get An Error Message Saying The System Is Non-modifiable. What Should We Do To Fix This?
In a DEV system, set the global system change option (SEO6) to modifiable for all namespaces/objects. The developers must have the ability to change any, including SAP, namespace/object. Change client options (SCC4) to “changes allowed for repos and cross-client cust” and radio button to “auto. save changes.” Next, enable CATTS sessions.
