Many thanks for your detailed information! I saw you had the same result that me… the recorded change log shows the ME52N what is the correct! but in PEI the recorded change log shows the ME53N what is very strange because this tcode is only for display purposes. Would be great if you can share us an example from PEI the next time that you have to adjust a purchase requisition, do you think that it would be possible in the close following days?
