I am quite new with arcgis and I am already frustrated by this tool. It's has literally no usability - or it's beyond my understanding.
What have I done:
1/ I have created a new map and added a layer with German postal codes.
2/ After that I have added a connection to this layer - combining a kind of aggregation of these postal codes
3/ Using the analysis function 'dissolve' I have created a new layer with these postal code aggregations.
But when I try to upload the map, it says that it's not possible to upload the map due to error 00230.
Can anyone tell me what I have done wrong or what this error is trying to tell me (it's hard for me because those support pages are not helpful at all...)
