Thank you, ArviLaanemets, for the feedback!

This is an interesting way to approach this project, I will have to start again and reconfigure to this structure!

However, this still doesn't give me what I'm looking for. In your example, each Task Card number is used twice, once in March and once in April. What I need to know is when the Task Card number is entered for April, that the same Task Card number was entered before, perhaps multiple times (so just the most recent entry), the (previous) Task Card Released Date and Version number that was released.
