Abstract:	This paper documents the implementation of a logical imputation based on the panel structure of the 2003 to 2008 waves of the German SAVE dataset. A new release of the waves 2003-2008 will be available from June 2009. The concept and the principles of the underlying logical panel imputation are described. Furthermore, the method applied to logically impute each variable is briefly commented. The logical panel imputation of the SAVE dataset reduces decisively the number of missing values for some variables. In some cases more than 50% of all missing values can be replaced by proper values.
