Hi Team, I have some queries related to best practice for Approved ICP Transactions

1) ICP Transaction was approved and Element Entry created. In case there was a mistake, what is the best practice for this?

a) Delete the ICP Transaction and Element Entry both and Submit a new Transaction? or something else?

2) As Admin, when using Administer Compensation Task from Com Work Area - There is a section showing Prior claims, ONLY the transactions which reside above this hyperlink are editable, those which appear post clicking the link, are not editable. Hence would like to understand what exactly drives this behavior.
