Error: 0xC0202009 at Data Flow Task, OLE DB Destination [43]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E21
My source is a TXT Flat File Source, the Destination is of type OLE DB. (see image)
I found a very basic tutorial on Code Project to create a package. I finished the steps but when debugging I get a strange error(bellow):
Can someone give an explanation to this error? It took me hours to search the web for the error.

The relevant error message
There was an error with OLE DB Destination.Inputs[OLE DB Destination Input].Columns[AppID] on OLE DB Destination.Inputs[OLE DB Destination Input]. The column status returned was: "The value could not be converted because of a potential loss of data."
Answer
So this error is occurring because you have a value in your source for the AppID column that is not valid for your AppID column in the destination.
Some possible examples:
- You're trying to insert a 10 character value into an 8 character field.
- You're trying to insert a value larger than 127 into a tinyint field.
- You're trying to insert the value 6.4578 into a decimal(5,1) field.
SSIS is governed by metadata, and it expects that you've set up your inputs and outputs properly such that the acceptable values for both are within the same range.
