When trying to revise a released assembly, a message dialog appears stating the assembly can not be saved.
Solution
This message occurs when the source / parent assembly is NOT up to date. To verify open the released (read only) assembly and review the structure with component tracker. Any line item(s) with a red asterisk identifies a condition where the parent is not current until saved, hence the informational message that the source can not be saved as it is in a read only (released) state.
