What does the flag Current Settings mean?
By default the production system is not modifiable and is not open for customizing.
Because of this you cannot do any modifications on the production system directly.
For that purpose you must use the SAP transport tool.
That means, all customizing will be done in the development system and transported to quality system and then to production system.
Often in business scenarios, there will be requirements which cannot be transported and which have to be modified directly in respective tables and other repository objects in the production system
For this purpose there is a flag in SOBJ transaction called Current Settings If this flag is checked, it bypassed the client settings and allows you to maintain data directly in the production system
Please note that the Current Settings does only work within clients with role Production.
Within clients with another role as Production the flag Current Settings has no effect.
