Resolve MailStream Plus- Mail.dat fields that are not populating cause error in PostalOne!



 
For the CRID and Mailer ID of Mail Owner (CPT-1149 and CPT-1148) PA INF parameter cards are used, and must be connected with the P ATTRs, as mentioned in the MailStream Plus Reference guide 8.2.1 page 149 for the PA INF parameter. 

If the PA INF card is not connected to a specific P ATTR then position 8 should contain 'L' as mentioned in the note referenced in the MailStream Plus Reference guide 8.2.1 page 149 titled PA INF-
NOTE: If you specify L for this field, then MailStream Plus uses only the PA INF to P ATTR Link field for matching. If this field is blank, then MailStream Plus uses both the PA INF to P ATTR Link and the P ATTR Code fields for matching.
