If an InfoObject has a reference InfoObject, it has its technical properties.
For characteristics these are the data type and length as well as the master data (attributes, texts and hierarchies). The characteristic itself also has the operational semantics. For key figures, these are the key figure type, data type and the definition of the currency / unit of measure. However, the referencing key figure can have another aggregation.
These properties can only be maintained with the reference InfoObject.
Several InfoObjects can use the same reference InfoObject. InfoObjects of this type automatically have the same technical properties and master data.
The operational semantics, that is the properties such as description, display, text selection, relevance to authorization, person responsible, constant, and attribute exclusively, are also maintained with characteristics that are based on one reference characteristic.
