Hi,
Waht errors are you getting?
What format is the source file you are trying to load?
Does the message file has the configured external status code in it, and do they match? The ACK status you highlighted does not show in your configuration.
You have selected pain.002_v3, but the message file you have displayed is not in pain.002 format.
These are some of the questions you need to answer before anyone could help.
