FIX: The generated XML files are much larger than expected when you try to split an EDI document that contains multiple sub-documents by using a "multiple" type schema in BizTalk Server 2006 R2 or BizTalk Server 2009

SYMPTOMS

In Microsoft BizTalk Server 2006 R2 or BizTalk Server 2009, when you try to split an Electronic Data Interchange (EDI) document that contains multiple sub-documents by using a “multiple” type schema, the XML files that are generated are much larger than expected. Therefore, system performance when BizTalk Server 2006 R2 or BizTalk Server 2009 processes large EDI interchanges becomes severely degraded.

CAUSE

This problem occurs because of a design change in BizTalk Server 2006 R2 or BizTalk Server 2009. BizTalk Server 2006 R2 or BizTalk Server 2009 introduces a new splitting behavior for EDI documents that contain multiple sub-documents and that are used with “multiple” type schemas. 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.

Note Because of file dependencies, the most recent hotfix that contains these files may also contain additional files.

The hotfix that is associated with this article enables a splitting behavior that is consistent with the splitting behavior of earlier versions of BizTalk and of BizTalk Accelerator for HIPAA.

As soon as the update is installed, the new splitting behavior is disabled by default. To enable the new splitting behavior, follow these post-setup instructions:

Un-deploy any registered multiple schemas.
Open the schema by using a text editor.
Add the following attribute to the "b:schemaInfo" node:
Split_Without_Sibling_Data="Yes"

This new attribute appears displayed under the "xs:annotation / xs:appinfo / b:schemaInfo" segment, just after the "subdocument_break="Yes" " segment.

The following is an example:

<xs:annotation>
  <xs:documentation xml:lang="en">HIPAA Schema TS834A1 - Washington Publishing Company (http://www.wpc-edi.com)</xs:documentation> 
  <xs:appinfo>
    <schemaEditorExtension:schemaInfo namespaceAlias="btsedi" extensionClass="Microsoft.BizTalk.Edi.SchemaEditorExtension.EdiSchemaExtension" standardName="EDI" xmlns:schemaEditorExtension="http://schemas.microsoft.com/BizTalk/2003/SchemaEditorExtensions" /> 
    <b:schemaInfo b:subdocument_break="yes" Split_Without_Sibling_Data="Yes" BiztalkServerEditorTool_Version="1.5" root_reference="X12_00401_834" displayroot_reference="X12_00401_834" version="3.0" standard="EDI" standards_version="00401" xmlns:b="http://schemas.microsoft.com/BizTalk/2003" X12ConditionDesignator_Check="Yes" /> 
  </xs:appinfo>

MORE INFORMATION

For example, when you try to process an incoming Health Insurance Portability and Accountability Act of 1996 (HIPAA) 837D interchange that contains multiple claims, the XML output from BizTalk Server 2006 differs from the XML output from BizTalk Server 2006 R2. In BizTalk Server 2006, the BizTalk Accelerator for HIPAA splits the 837D EDI file. The EDI engine then translates the EDI file into multiple XML files. The EDI engine generates one XML file per claim. Each XML file contains only the data and the XML markup that pertains to the claim.

However, in BizTalk Server 2006 R2, the EDI engine splits the 837D EDI file. The EDI engine then translates the file to multiple XML files in which each claim file contains additional XML markup. In this case, the resulting XML file contains the expected data for the claim. The XML file also contains empty XML markup for all sibling claims that are found in the original interchange.
