This only concerns multiple branches.
You now need to decide who can see/share what information. Sharing information across locations can be seamless but, should you choose to, you can restrict what information can be viewed by your negotiators. We need to have configured your branches for you, but once we have done this, go to Business Configuration > Data Sharing and tick the boxes to choose which bits of data get shared with which branches.
You may need to repeat this for each branch if it is going to be different.
