what is a worklet?
Can u access a repository created in previous version of Informatica?
Hi, I've a mapping with flat file source The target update override property for the target table is using update stmt. There is no update strategy between source and target. Also The session has the target properties as Insert , Update as update options checked. Does this mean that recs will be inserted only and the update override will not be applied at all. Thanks
