Hi Adam & all,
My understanding is : maintain the info at the source (an upstream reference system). If it will eventually come from GAWSIS, then this is where you need to maintain it.
In Offenbach I understood these imports from JCOMMOPS / WRD or GAWSIS have so far only been punctual as opposed to regular. They should become regular when the machine interface is ready.
EC70 gives some calendar indication for this machine interface : operational before end of the year.
