F110 proposal has been cancelled

Hi Experts,

Would like to ask possible reasons the following status is displayed in F110.

Parameters have been entered

Payment proposal has been cancelled immediate message is once press the create proposal...

and if I am trying to findout what is the possible reason to access the Proposal Log it will give the message: Proposal Log has been not found.

What are possible reasons the payment run was cancelled.

Cheers,

Raja.A
