Table name too long

We're creating naming conventions for a schema to use for various tools, and are running against Table Name too Long errors when using Power BI Desktop Report Server (January 2019).  I have not found documentation that shows the limitations of either Table Name or Column Name length for Power BI Report Server (or service).  Can someone help us find this?  We don't want to use illegal characters either.


Tried Direct Query and Import on a table name of 128 characters that is not failing using other tools. 


DataSource.Error: ODBC: ERROR [HY090] [Microsoft][ODBC] (11400) Table name too long.


Thank you for any help you can provide.  We need to document the requirements, and I am not finding on any MS whitepapers.

Re: Table name too long

Thank you for your reply.  We are testing the already created table name and columns in Netezza and realize this is the limitation there.  My question is what is the Power BI limitation so that I can't use the table as a data source from Power BI?  Our other tools allow it (SAP for example). 


We are trying to determine the lowest number of characters allowed, illegal characters, etc. so we don't face problems later on.
