TSW0003 is the delivered Swedish LOGO panel.
During initial TPX installation, part of the process is to copy samples into the TPX VSAM files. Part of ADMIN1 is a sample for Terminal Options that specifies an alternate LOGO panel of TSW0003 to the usual TEN0003.
If you don't have Swedish language installed (FMID CB0V54F, DSN *.CB0VPSVE) then TPX won't find TSW0003 and substitutes the delivered default TEN0003 or what you have specified in SMRT.
If you are creating your own rule based upon one of the installed samples, you should specify the actual LOGO panel that you would like displayed. You can leave this field blank.
