Hello Robin,
thanks for your answer.
I'm so sorry it wasn't clear.
The datas in the first post are only imported data. The pages of this template will only contain imported data. They are used by an other template which references with a Page Reference field to the title (=customer-ID)
CSV-Data of the first post looks like this:
title,VKGRP,KUNNR,ANRED,NAME1,NAME2,STRAS,LAND1,PSTLZ,ORT01,ORT02,TELF1,TELF2,TELFX,AUFSD,BRSCH,KATR7
1000010,42,1000010,Firma,Mustermann GmbH,Schreinerei,Dorfstr. 77,DE,77777,Dorsten,Lembeck,02369 / 7777,,02369/7777,,12,NE2
You see, the value NE2 is already existing.
But most of the editors doesn't know the label of NE2, that's why I want to display it.
