Find msg id with the help of IDoc number

Hello Experts,

Please help me with this issue.

I found msg ID for an inbound IDoc to an ECC system with the help of WE09 tcode. but I need to find the corresponding msg ID in PI.

The message ID we find in the DETAILS tab for an IDoc in WE09, is that the one ? Because I tried searching for that message using the ID but I cannot find that. If not, then how can I find the corresponding msg id for that msg in PI ?

Please help.

Thanks,
