I have following query to start of with:

```
Select *
from AAF21OKN$                  
where Service like '%AAF21%'
  OR Ydelse like '%UXM%'
  OR Ydelse like '%UXU%'
  OR Ydelse like '%UXR%'
  OR Ydelse like '%UXZ%'
Order by [Patient ID], [Date]

```

I then get following table (only a snapshot for better desciption):

```
Patient ID    Date                      Service
----------    -----------------------   ------            
Forløb08196   2020-03-04 00:00:00.000   UXMG25
Forløb08196   2020-03-06 00:00:00.000   AAF21 OKN
Forløb08196   2020-03-06 00:00:00.000   UXRG25BES

Forløb10030   2020-02-03 00:00:00.000   AAF21 OKN
Forløb10030   2020-02-04 00:00:00.000   UXMG25

```

I now have a problem:

* I only want to show the services where the service starting with 'AAF21 OKN' is first (by date).
* Patient ID: 'Forløb10030' is for example what i want.
* But in Patient ID: 'Forløb08196', I don't want the Service 'UXMG25' row to be showed. As it has happened before the service 'AAF21 OKN'
