Dear Techies,

I want to create the reginfo file under /usr/sap/SID/DVEBMGS01/data/....in which i want to add the data as per note 1850230

#VERSION=2

P TP=<program ID> HOST=<external host> CANCEL=internal,<external host> ACCESS=*

...

# the following lines should be the LAST lines in the reginfo

#

P TP=* HOST=<LIST> CANCEL=<LIST> ACCESS=<LIST>

P TP=* HOST=local

I am not getting what to add in this program id , Host and internal external host names,

Please suggest...
