Defining the Order of Entry Points 
Use
If your Enterprise Portal has multiple roles/worksets and you want to define the order of the entry points on the navigation bar yourself, you can define priorities for the entry points.
Keep in mind that you cannot define the priorities for individual users. The priority is always defined for one view in the portal and only make sense if all your users are assigned to the same roles and all of them have the same view in the portal.
Prerequisites
Principles of Defining Priorities
You define priorities for the entry points by assigning a certain value to each of the entry points. You may only define values greater than 0 for the priorities. You can also specify numbers with decimal values, for example, 1, 1.5, 1.75, 2 and so on.
The smaller the value of the entry point, the further left it moves on the navigation bar, that is the entry point with the lowest value appears to the far left and the others follow in the order of their priorities. The entry points without a priority appear in any order.
Note that SAP Portals already delivers roles and worksets with prioritized entry points. Remember this when carrying out your own priority definitions:

The more often a point of entry is used, the further to the left it should be placed (in other words, the smaller the value it is given should be). For example, 20 should be used for entry points that are used daily, and 29 for entry points that are rarely used.
If you want to place two entry points next to each other, you should use a priority of 20.1 and 20.2, for example.
Procedure
Result
You changed the random order of the entry points in the portal to suit your requirements.
Example
For example you can decide that entry points F1 and F2 of role 1 should appear in the second and fifth location, entry points F5 and F6 of role 2 at the sixth and fourth location, and entry points F8 and F9 of role 3 at the first and third location of top-level navigation. The following graphic shows how you should define the priorities for the entry points so that they appear in the desired order in your portal.
