Today eOne has released a hotfix for SmartConnect 2010 for GP 2010. There are two main issue addressed in this hotfix:
1. Random 'Write Failure Error' when running SmartConnect maps after upgrading to eConnect 2010. This issue is reportedly resolved with SP1 eConnect but in our testing this issue still arises - albeit less often. This build of SmartConnect will track for this specific error message and reprocess failed document containing this error. In our testing this has resolved the issue in all cases.
2. Dates passed to the CRM webservice will be of a standard CRM acceptable format rather than the format defined on inidvidual servers. This issue impacted customers with a non USA date format server, and a USA based CRM install.
