I am sure we had this Problem some time ago, but i do not find the posting and also not the solution.
I have SD and also teh DFS-subscription. It is not that straight forward, as I have now the official germain AiP and also the DFS-plates in separate chapters and documents.
For France e.g. I can find alsways a document "textual Information" even for smaller aerodromes containing opening hours, phone numbers and so on.
For german aerodromes I do not find this information - only for the IFR equipped airfields.
AFAIK this Information is summarized in ONE document instead of a document for every airfileld. But which? in chapter AD of the AiP, I do not find this.
Can someone help ?

BTW: I now find many airfields in Germany with geo-referenced Taxiway Charts. i cannot remember when this came. is this a Feature of my DFS-subscription or from the AiP or SD?‌‌‌‌‌‌‌
