For those of you who are using the multiple schema to split your claims up into individual messages, you might have come across the performance degradation issue with having those messages come into the message box.

This functionality worked fine using the Covast HIPAA Accelerator, but seemed to be a huge issue when migrating to R2.

This is the cause that Microsoft states:

The splitting behavior results in XML files that include not only the sub-document that you want, but also empty XML markup for all sibling sub-documents. Although the sibling sub-documents do not contain data, the behavior results in bloated output XML files and other inefficiencies that make processing very large EDI batches impossible.

I think it is interesting that something is impossible – wow!

To make the impossible possible again, you need to install hot fix 967945, you can download it in the View and request hotfix downloads link.
