By activating the checkbox in the table header, all referenced objects will be selected. Single objects can be selected by activating the checkbox in the corresponding row.
The title of the referenced object is shown here.
For each object, a symbol is shown as to whether the object is included in the import packet, it is already on the target system, it is in both the import packet and on the target system or it is in neither the import packet nor on the target system. If an object is only on the target system or cannot be found, then it cannot be selected for import. The referenced object cannot be imported if the reference cannot be found. The corresponding information is shown in a quicktip when you move the mouse over the symbol.
