You receive an error in the event log similar to "index was outside the bounds of the array" when validating or sending an EDI document

Problem

When you try to validate an EDI document or when you try to send an EDI document in Microsoft BizTalk Server 2006, an Error event that resembles the following may be logged in the event log:

Event Type: ErrorEvent Source: EDI TransmitterEvent Category: BizTalk Server 2006Event ID: 27Description:Transfer of message(s) to EDI Subsystem failed. Index was outside the bounds of the array.

Cause

This issue occurs if one of the following conditions is true:

· The BizTalk Base EDI service and the BizTalk Server Host service do not use the same logon credentials.

· The logon account for the BizTalk Base EDI service and for the BizTalk Server Host service does not have the permissions that are required to access the BizTalkEDIDb database and the Configuration database.

· The user who configured the EDI adapter is not a member of the EDI Subsystem Users group and of the BizTalk Server Administrators group.

Resolution

The user account that is configured as the logon account for the BizTalk Server Host service must be a member of the EDI Subsystem Users group. If the user account that is configured as the logon account for the BizTalk Server Host service is not a member of the EDI Subsystem Users group, the EDI transmitter cannot connect to the EDI subsystem because of insufficient permissions. Therefore, the Error event in the event log states that there is a transmission failure.

To resolve, try one of the following methods:

· Verify the service logon credentials. Verify that the BizTalk Base EDI service and the BizTalk Server Host service use the same logon credentials.

· Verify the database permissions. Verify that the user account that is configured as the logon account for the BizTalk Base EDI service and for the BizTalk Server Host service has the permissions that are required to access the BizTalkEDIDb database and the Configuration database.

· Verify the group membership. Verify that the user who configured the EDI adapter is a member of the EDI Subsystem Users group and of the BizTalk Server Administrators group.
