Hey @hankal1 if you're still getting this might be related to permission. Try to check the network call failing in the browser console when clicking on save button, I believe you will see "Unauthorized" in the failed request response. If this is the case, then check the following -
- The report suite, dimensions, metrics and DW permission should be under same product profile. For example let us say you have two product profile : Profile A and Profile B.
Profile A - Has a report suite A, with all dimensions, metrics, and DW Tool permissions
Profile B - Has a report suite B, with all dimensions and metrics but this doesn't includes the DW Tool permission.
So, here you should be able to save DW request for report suite A, but when trying to work report suite B, it might result in this particular error.
Hence, it is suggested to have a single product profile, which includes all report suite you required access to, along DW Tool access within the same product profile.
Also, if you're a product admin, this should bypass these check and you should be able to save the request.
