The BizTalk Adapter for Host Files doesn't process BizTalk Receive Location SELECT statements together with UPDATE or DELETE statements. This causes BizTalk Server to log the following entry in the Application log:
Distributed Data Management Record-Level Input/Output error INVRQSRM ("Invalid request")
This problem occurs because the BizTalk Adapter for Host Files requires a specific way to write select and update statement. If this process is not implemented correctly, the Receive handler does not process UPDATE or DELETE statements.
Cumulative update information
The fix for this problem is included in cumulative update package 5 for Host Integration Server 2013. For more information about how to get the cumulative update package, see Cumulative update package 5 for Host Integration Server 2013.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
The Microsoft BizTalk Adapter for Host Files runtime and Microsoft DDM Client for Host Files have been corrected to set access intent for UPDATE or DELETE when it processes a SELECT statement together with a positioned UPDATE or DELETE operation.
