Change Purchase Order Layout

Sup Boys ‘n Girls,

In the current PO report layout that we are using the article number does not fit into one line so it automatically breaks down to the next (see annex). That fact has already caused some misunderstanding with suppliers as they did not expect the article number to continue in the next line. 

Is there a way of highlighting the article number (e.g. put a frame around it) or let it fit into one single line? 

Any support is appreciated. Thanks!
