how to get Postage Statements in TEM or PostalOne! sites from MailStream Plus (MSP)

The option to generate a Postage Statement from your Mail.dat files on the TEM and PostalOne! sites will be 'N' (for no) unless the Mailing was indicated as 'Ready to Pay'.
The 'Ready to Pay' status is set using the second field of the xx INF subkeyword MDMFDD.  MDMFDD can be used on RP INF, EP INF, or BATINF parameters.   Put an R (to indicate 'Ready to Pay') in position 12 of the Information Data area.  That will populate CSM-1124 with an R. 
Then generate new Mail.dat files.  Upload them to TEM or PostalOne!, and verify whether you are now able to generate Postage Statements.
