Dataflow Gen2, MashupException.Error
Hi everyone, I'm new to Fabric and try some basic experience. Now, I try to create a warehouse in Fabric as truncated from Microsoft AdventureWorksDW. I want to create a table Product using Dataflow Gen2 from 3 tables from AdventureWorksDW: DimProduct, DimProductSubcategory, DimProductCategory. I need only few fields: ProductKey, Color, EnglishProductName, EnglishProductSubcategoryName and EnglishProductCategryName. I setup Dataflow to return such table. I created the table in my schema with column names above and needed datatypes (ProductKey - int, other - varchar) using SQL and set Data destination in Dataflow Gen2 to that table. When Dataflow published and run, it is failed with error: Mashup Exception Data Source Error Couldn't refresh the entity because of an issue with the mashup document MashupException.Error: DataSource.Error: Microsoft SQL: String or binary data would be truncated (see attached picture). On https://community.fabric.microsoft.com/t5/Dataflows/Couldn-t-refresh-the-entity-because-of-an-issue-with-the-mashup/m-p/3514804 I found similar question, but solution is a little crazy and does not work for me. Q: Has anyone else had such error? How to handle it? Thank you!

Hi @Will Needham , thank you for your answer! It helped, but not directly :) I fixed it with 2 steps: 1. check MAX(DATALENGTH(`column_name`)) in data source and specified data types in Fabric Warehouse using that information. (before it was just "varchar" without specified byte length) 2. removed unnecessary columns from other tables (Subcategory and Category), which also uploads in default dbo schema. It helped and now it works. Thank you again!
