At the end of the processing block END-OF-SELECTION, delete the contents of one or more fields you previously stored for valid lines using the HIDE statement. At the event AT LINE-SELECTION, check whether the work area is initial or whether the HIDE statement stored field contents there. After processing the secondary list, clear the work area again. This prevents the user from trying to create further secondary lists from the secondary list displayed</P><P></P><P></P><P><STRONG>Cheers,</STRONG></P><P><STRONG>Chandra Sekhar.</STRONG></P></BODY></HTML> Sun, 09 Mar 2008 09:09:25 GMT https://community.sap.com/t5/application-development-and-automation-discussions/valid-lines/m-p/3492239#M839896 Former Member 2008-03-09T09:09:25Z
