I got an urgent issue here. There are 4 payment methods exist in the backend system. On my ESS, we can also find 4 payment methods when we maintain Bank information. The problem is that the client do not want this happens. They want to make the Payment Method field is defaulted and non-selectable, which means one and only one default payment method will appear on the portal and the employee have no chance to choose any payment method.
BTW, I am using WebDynpro version ESS.
Can anybody help me on this? Many thanks!
