OLE DB or ODBC error: Exception from HRESULT: 0x80040E4E and Column contains a duplicate

Hello, 
 
I am facing an issue when refreshing the datasets and am quite lost. The erros i get:
 
1. Combined reporting data
OLE DB or ODBC error: Exception from HRESULT: 0x80040E4E.
2. Combined planning data
Load was cancelled by an error in loading a previous table.
3. All Employee date
Column 'GPN ' in Table 'All Employee date' contains a duplicate value 'konsultants' and this is not allowed for columns on the one side of a many-to-one relationship or for columns that are used as the primary key of a table.
 
Regarding problem no. 3: found no duplicates in my table:( Could someone please advice what is possible to do? Happy to provide more info if needed

Hi @Anonymous ,

 

“Regarding problem no. 3: found no duplicates in my table:”

Suppose you establish a 1:* relationship for two tables, then refresh the data and the table on the 1 side will be refreshed to contain duplicate data, then this type of error will occur.

So you need to check your data source. If the two tables in the data source have been updated to *:* relationship, then an error will be reported when you refresh.
