OSP Return Days Setup(India Localization)

Hello,

For the India Localization one has to setup a value for the field OSP Return Days under common configuration.As per some Oracle university videos that we saw they are saying this value should be 1(input material) or 3 years(capital goods) worth

of days.

We have the following doubts

1.Does this setup have to be absolutely 1 or 3 years or can it be any value like say 2 years or 5 years or 10 years(based on the business' decision) after which the system will not let you receive the OSP PO?

2.Secondly if the OSP PO does exceed this threshold , how do you receive that OSP PO as an exception?Is there a manual workaround to account for that OSP PO that has crossed that threshold set in the above parameter?
