During the run of an Integration Services Solution, if you see the error below, analyze the message carefully.  What seems like an Invalid ID Error or a truncation error, may in fact be a field type error.

The error below looks like a truncation error, since the actual Key value in the example used to generate the error is  ABCD0000000UMEAAA4 and in the error code returned field value does not match.  It is missing the AA4.

However, if you look further, the error references that the Solution is attempting to pass this ID in as RecordType1, indicating that the ID was wrong for the TYPE RecordType1, not that the ID was invalid.  If you see this error, make sure you are using the right ID and the right object.
