Hi Anestis,
the easiest way is to use the "Coordinate Dimension 17" library part (I hope it exists also in your localized library).
Once you defined your points by using this object you can easily create an Interactive Schedule Element List where:
the criteria should be
Element Type = Object
Library Part Name = "Coordinate Dimension 17"
The fields:
ID (you find it under Object/Lamp parameters)
Coordinate X
Coordinate Y
Coordinate Z
(these 3 parameters can be add by clicking Add Object Parameters button, finding and selecting the "Coordinate Dimension 17" and adding these parameters from its list).
The result will be the one showed in the attached image.
The result can be exported on several file format.
Friendly
