I have a SP 2010 workflow that prompts information from the users, and a timer job which reads data from a constantly-updated DB. They both add data to another list item that stores the most recent business information.
Edit: To clarify, these list items are a sort of dashboard that aggregate information from several sources. Thus, both the workflows and the timer job will access the same list item (but the items will be different for different workflow instances). The workflow and the timer job will modify different fields.
Is there any chance of synchronization errors between the concurrent updates? Can user-entered information be lost? How do I go about synchronizing the workflow and timer job, and what other pitfalls should I look out for? Thanks.
