Good afternoon, Denis.
Most likely your business process direction is "Incoming". The direction can be viewed in the business process itself here
http://prntscr.com/utgjp3 http://prntscr.com/utgk22If this is an order to the supplier, then the direction should be "Outgoing".
Accordingly, the "Update our commitment to the customer" action updates your payment commitments.
And the action "Set/update the obligations of the client (to your company)" updates the obligations of the client (in our case, this is the supplier) regarding postings.
If you have a regular order to the supplier Ordered-Paid-Capitalized-Closed, then you can put 100% in the actions of updating obligations and everything (without checkmarks) will then also be correctly calculated.
