Dynamics GP2015 and Integration Manager: SOP Sales Invoice Entry with Batch of 10000 lines

Hi,

We are trying to integrate a single SOP Batch with 10,000 Lines in it.

For some reason it fails at 1037 lines! or about 1 hour into the integration process.

Checked all the trans and there are no errors in format or data.

Has anyone tried such large tranx batches using Integration Manager in GP?

The error is as listed in this post;

https://community.dynamics.com/gp/b/gpmarianogomez/archive/2011/01/04/im-troubleshooting-rpc-errors-when-running-integration-manager

We even tried it directly on the client with both GP and IM installed on the same machine and it fails.

Any insight is appreciated!

thanks much,

Thomas S.
