Hi Daniel ,
I am unable to relate to the screenshot . You should be able to make the field invisible in either of the 2 ways :
1. Webdynpro component level
2. By Meta data concept .
Also do you not use the sourcing cockpit functionality wherein the PO after getting approved would move to the sourcing cockpit where in you can create a PO .
Please also send a detailed screenshot which Tab of SC screen do you see the button ?
Regards
Vinita
