Error updating dataflow

[Anonymous]

Hello community, I'm having a problem creating tables in dataflow. When making the connection to the sql server, and extracting the tables any merge or other interaction that I do with two tables appears a symbol in the table (yellow ray), and with that when saving it does not return me error. but in the update of the dataset it does not let update.I'm using a Premium license

I think the types of flows I already know, thank you very much, but that's not the problem I'm trying at the moment. since the problem is the non-updating of the data when having an entity computed .Any merge between tables generates a computed entity, generating the non-update.

The lightning bolt is for computed entities. Please see this documentation.
