per dimension there are a number of account numbers.
Now the titles "OMZET", "DIV+FIN OPBRENGSTEN" etc. should be the dimensions.
Now the numbers would be linked as %key_Rekeningno to the existing structure.
So If i make a pivot table, I can include all the dimensions as said above, then underneath them should be the account numbers (also as dimension I guess) and then the measures next to them per category.
