Potential duplicate invoices in MM is blocked through an error message
I need assistance with active message types, I know that E stands for Error, W is Warning am not too sure what "I" stand for, when I check on SAP message type the description says I is "Note in window". However this description is not good enough as I am still note sure what it really means. Can someone kindly help me understand what it means.
Your assistance on this regard will be highly appreciated. Thanks in advance.
