  The SAP error message 28550, "Error in compilation of dependency &1: Char. key missing from line &2," typically occurs during the activation or compilation of a data dictionary object, such as a table, view, or structure. This error indicates that there is a missing characteristic key in the specified line of the object, which prevents the system from successfully compiling the dependencies.
