2.4 Process PDE Messages

This topic provides an overview of the PDE validations on SWIFT messages.

The system detects the messages (Incoming/Outgoing) as PDE messages by performing the validations. The Incoming and Outgoing PDE messages are processed by the system in the following manners:

Incoming PDE Messages

In the case of incoming messages, EMS picks up the incoming messages and inserts them into a data store. If the incoming message has a PDE trailer (message contains the text PDE) then the system will mark the process status as Stopped due to PDE. After due validations, release the message from the incoming PDE message queue. Once these messages are accepted they will continue to get uploaded as a normal messages. If the PDE trailer is not present in the incoming message, then the message upload will continue as normal.

In the case of incoming messages with a PDE trailer, the PDE Flag check box in the Incoming Message Browser screen will be checked.

For more details on the PDE indication of an incoming message in the Incoming Message Browser, refer to topic Processing income message section.

Outgoing PDE Messages

In the case of outgoing messages, follow any of the following if the system detects a message as a duplicate based on the PDE validations:

• Auto release the message with the PDE trailer
• Release the message without the PDE trailer
• Reject the message

The system displays an override when it finds a message to be a duplicate one. In this case, the message is parked in the PDE queue and either does release the message without the PDE trailer or with the PDE trailer. If the message is released with the PDE trailer then the message is appended with PDE, else the message is released without PDE. The messages can be rejected. In this case, the message status will be changed to E(Exception) and this will not be picked up by EMS (Electronic Messaging System).

Due to message size restrictions, sometimes a single message is physically split into multiple parts and each one is stored in a distinct record in the outgoing message data store. A message is marked as PDE, if all the split messages are found to be duplicates.

Note:

All the messages in the PDE queue (Incoming and Outgoing) are completely processed by EMS before initiating EOD operations.
