Was the long text to the error message not clear enough?

"This block could not be set because in the warehouse number concerned there are already material blocks, that is, it is most likely that stock postings are currently taking place."

In my words: 2 trains cannot use the same single track at a time. 2 users cannot change the material master at the same time. A movement changes stock values in a material master. Just wait until the movement is done, or until somebody else has closed MM02 for this material.
