ABAP/4 Program: Describe Select-Options

When printing a report, you can print the search conditions or report parameters that the user entered. For instance, if a report output was restricted to plants between 1011 and 1501, you may want to print "Plants Between 1011 and 1501" on the report. This procedure describes the selected parameters.
