I have created Purchase Requisition in Me51N and saved it,
now i go to ME52N and in item level in Valuation TAB i am changing the valuation price(for Ex 3 now i am changing to 4rs)3rs is coming from material master accounting 1 view)
if i change to 3 to 4 rs and saving it is changing and PR is saved.
here my requirment is the valuation price should not be changed,if i change from 3rs to 4 rs the PR should not be saved in ME52N
what is the solution for it is not allow to change the price in valution tab,if i change the PR should not be changed.
