A couple of weeks ago, a client was testing Microsoft Dynamics GP 2010 R2 and reported that some of their postings from an external system were not arriving in GP (these postings are transferred using eConnect).
When I installed eConnect I enabled Journalling on the econnect_incoming queue so we would have a record of messages which had been submitted. After receiving the error I went to make sure the messages had reached the GP server ();
Postings to Payables Management and the General Ledger were showing in the list of journal messages so the next step was to check the Event Viewer for eConnect ();
There were three errors showing up for eConnect all with the same error description;
The full error description;
eConnect Incoming Service Version=11.0.0.0
Message Label:PaymentPostingBatch844

I did some investigation and couldn’t really find anything relevant to Microsoft Dynamics GP and eConnect but some suggestions in general that this may be a timeout issue. I hunted down the configuration xml (span class=’path’>C:\Program Files\Microsoft Dynamics\eConnect 11.0\Service\Microsoft.Dynamics.GP.eConnect.Service.exe.config) and looked for the following section;
<binding name="eConnectNamedPipeConfig" closeTimeout="00:10:00"
sendTimeout="00:02:00" transferMode="Buffered" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
<readerQuotas maxDepth="60" maxStringContentLength="2147483647"
maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
<security mode="Transport">
<transport protectionLevel="EncryptAndSign" />
</security>
</binding>
I amended the two timeout values (highlighted below) and made them both 20 minutes;
<binding name="eConnectNamedPipeConfig" closeTimeout="00:20:00"
sendTimeout="00:20:00" transferMode="Buffered" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
<readerQuotas maxDepth="60" maxStringContentLength="2147483647"
maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
<security mode="Transport">
<transport protectionLevel="EncryptAndSign" />
</security>
</binding>
Unfortunately, the above setting was still resulting in an intermittent error. Even more unfortunately, my part in the investigation ended at this point as I left the company for a new opportunity and this blog post remained incomplete.
My former colleague, Andrew Cooper, took over the investigation and has kindly emailed the solution. He found the answer on the PartnerSource Knowledge Base, by searching for a slightly different but related error message, in KB article 2539263 (available to everyone on the Microsoft Help And Support site) and has kindly passed the answer onto me so I can complete this blog post;
<binding name="eConnectNamedPipeConfig" closeTimeout="00:20:00"
sendTimeout="00:20:00" receiveTimeout="infinite" transferMode="Buffered" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
<readerQuotas maxDepth="60" maxStringContentLength="2147483647"
maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
<security mode="Transport">
<transport protectionLevel="EncryptAndSign" />
</security>
</binding>
The issue is that the WCF service-oriented application can remain active for only ten minutes without activity after which it is dropped. The above change, adding receiveTimeout=”infinite”, keeps it active and prevents the error we were seeing.
