Metadata regenerate: Value could not be converted because of a potential loss of data.

Hi

I already reviewed other threads but I dont find any solution. The thing is that it works in "some source-->destination"  properly and it doesnt in someo thers.

the source comes from stored procedure that sends back a select statement. the size is varchar100 as the destination table.

Here comes the error:

[Fuente Datos Cust Ledger Entry [1061]] Error: There was an error with Fuente Datos Cust Ledger Entry.Outputs[OLE DB Source Output].Columns[CompanyID] on Fuente Datos Cust Ledger Entry.Outputs[OLE DB Source Output]. The column status returned was: "The value could not be converted because of a potential loss of data.".

I checked the arrow between source and destination, into the metadata and noticed that seems incorrect, its DT_I4. But its DT_STR in the proper ones so this could be the problem. How do I fix this? tried to delete arrow, create again... didnt work.
