It seems I may not be the only one wishing for information and resources on the ins and outs of getting custom reports that work in SSRS to succeed when I push them out of the nest and onto the CRM report upload.
I've had issues that took a while to figure out, and nothing much to go on. Upload - data source issues, Subreports that can't be viewed outside SSRS, if it can go wrong it has.
So let's ask everybody! Please reply with anything you found helpful.
Just paying someone who knows the answers is probably not going to help anyone else :-).
Thank you all.
