PO Release strategy Workflow issue

Hi All Workflow Experts,

I need a help in one of the workflows in our project.The workflow is for PO Release Strategy.The problem is in the Production environment and is as mentioned below:

''Users are complaining of irrelevant mails with subject "PRD: PO auto release code" delivered to their lotus notes inbox from SAP workflow. Mail does not carry any further details like whats the PO number etc. In some cases this mail should not be delivered to the recipients as they have nothing to do with PO release strategy approval process.''

As I am not very old in Workflows I want to know where should I start from? I mean what all are the possible

areas where I should look into? Also this issue cannot be replicated in QA environment? So is there any environment specific thing I should do?

Please advice.

Thanks,

Saket.
