SAP B2B addon output format issue

Hi All,

we are migrating PI 7.1 to PO 7.4 single stack where all Seeburger B2B scenarios have been changed to SAP B2B.

Below are the output comparisons of both

In SAP B2B add-on I'm getting additional characters "++", any impact with these special characters or can we remove these characters from file??

Can anyone suggest the solution for this ASAP.

Regards,

Sateesh
