Executing Post-Install option 3 DB2 Catalog Customization task encounters the error message:
ISPP290 Panel 'INSSLDB2' error The EXPAND designation is improperly used within the panel record. Panel line where error was detected: + SORT SSID\SETUP+= Reorder rows
The cause of this error condition was due to running the Post-Install 'convert vertical bar' job (found under the INS task in Post-Install option 2 File Tailor). This process modified the INSSLDB2 panel member changing '?SORT SSID|SETUP' to 'SORT SSID\SETUP'.
Manually edit the INSSLDB2 panel member found in highlvl.CDBAPNL0 panel library to modify the '\' back to '|' for that statement or reload the highlvl.CDBAPNL0 panel library with the contents of the highlvl.ADBAPNL0 panel distribution library.
