Hi,

I have trubel with my Excel Connection manager. I get error about "VS_ISBROKEN" and "A destination table name has not been provided".

The foreach Loop finds the folder and loops correctly and has DelayValid as True

I have one string variable.

Excel Connection Manager has

DelayValid is True 

Expression

Connection String and Expression:

"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + @[User::strExcelFile] +  ";Extended Properties=\"" +"Excel 12.0 XML;HDR=YES\"; "

The data flow task has:

DelayValid True

Full Error code:
