Delete table contents before import
This option is available only when using R3trans with "Export" command. It does not affect the data at the export. When the R3trans file is used lateron for "Import", the data of the table(s) will be deleted in the SAP system before the data will be imported from the R3trans file.
In case you reduced the data of a table to be exported with a "where condition", for this table no deletion will be done at the import.
