DataSource.NotFound CRM Dynamics Online Odata feed issues
Thanks Greg_Deckler ... It's not the connection string, as it happens after the initial data has downloaded to the query. There are a few issues I think I'm facing - the IncidentSet has 290+ rows (and appears to be growing!) so even when I've limited the columns there is still a lot. Once I limit the columns, I either get the 404 error when trying to certain tasks (eg check for error rows) or I only get 51 rows which indicats a error in the row somewhere... but I cannot check for errors as this appears to also send all columns to the OData query.
I have also found in the MS CRM OData reference that the string for the OData feed is max'd out a 2048 characters... so this could be contributing to the problem. This evening I'm going to reduce everything to a few columns and see is I can at least get a condensed dataset to work..... I think there might be a few things going on at the same time here, possible data issues and an OData string that too large (3380 characters)... will keep posting as I discover...
Ah yes, I do remember getting some random 404 errors for LeadSet when I was trying to grab every column in Leads, it would only get so far and then error out with a 404. When I reduced my columns, it worked like a champ. I think I even made mention of that here:
I would definitely reduce the URL lenght if at all possible but seems you are on the right path to troubleshooting it. I think everyone in the community would be interested in you results if you can get past some of the issues as I have seen this issue come up before.
