Using two feature layers A & B, I have a query on A to filter records out, then join it to B to updated field values through a series of calculates. My output is B but DP errors out giving me the message 'The selected layer does not support updating existing features'. B is editable and updatable otherwise outside of DP. Is this due to the being joined in the earlier part of the DP? The work around to create a copy to join so the output is different?
Thanks
