FIX: Batched and unbatched messages log event 4119 as an informational event in BTAHL7, or the whole batch is suspended if any message contains a parsing error

Symptom 1

When the Microsoft BizTalk Accelerator for HL7 (BTAHL7) receives an HL7 message type, you see an event log entry that resembles the following:

Event Type: Information
Event Source: BizTalk Accelerator for HL7
Event Category: None
Event ID: 4119
Description:
An empty batch was received with fragmentation turned on. The 1st 1kb of the message is MSH|^~\&|SOME_SOURCE^^|4265|||...

This problem occurs even if you have disabled the Fragmentation required option for the source party's Incoming Batch field. Therefore, excessive logging may occur. Additionally, a security issue may occur if a confidential message is exposed.

Symptom 2

In a batch-in-batch-out (BIBO) scenario, if any message in the batch contains a parsing error, the whole batch is suspended.

Fix for symptom 1

To prevent the excessive logging of event 4119, an Event Log Successfully Received Message option is available on the Global Settings tab under BTAHL7 Configuration Explorer.

When only the Event Log option is enabled, BizTalk Server creates warning event logs and error event logs. When the Event Log Successfully Received Message option is also enabled, BizTalk Server creates information event logs that contain event ID 4119 according to the following table:

Fix for symptom 2

To address the BIBO issue, a Recoverable interchange support required option is available on the Batch Definition tab under BTAHL7 Configuration Explorer.

When this option is set to True, processing completes even when a parsing error occurs in a message in the batch. BizTalk Server delivers successfully parsed messages in one batch. Additionally, BizTalk Server generates an acknowledgement (ACK) message. BizTalk Server individually suspends the unsuccessfully parsed messages. BizTalk Server generates a single ACK message to identify the errors for all the individually suspended messages.
