/sapapo/tscopy giving error

Hi I am running the above transaction report and getting error that cvc doesnt exist for target MPOS whilst the target MPOS contains the cvc.

Current grouping selection is only zsku, I changed the grouping selection to location(9AMATNR) and its working. The characteristic assignment and keyfigure assignment is correct but the characteristic length for source and target and number of navigational attributes is different.

Attached images, Please guide!!
