I need to create a custom payment block on invoice based on certain situation like PO creation date is greater than invoice creation date etc. This block needs to be displayed and users should be able to release thru MRBR transaction just like other standard blocks. All standard exiting block reasosns (quantity, date, price etc) are already in use and I can not use them for my purpose. How can I create a custom block reason which should block Invoice for payment and should be able to realease the block through MRBR.
I have seen similar questions raised in the past but no solutions/answers. Please advise, will appreciate.
Thank you,
Madhavi
