someone tell me if you know how to block the "net price" on Trade ME21N through customization?
If possible, could someone tell me how to do this?
And to make the calculation of the price which exit have to use?
You can Restrict Users to Enter Net Price in Purchase Order Creation ME21N and the Price is Pulled automatically thru Purchase Info Record.
Go to OMET Functional Authorization and Create New One and in Field Selection control key assign $DE1 and Put tick mark against Display Conditions so that User cannot Enter Price in Item details Condition tab also.
Later you have to assign the User Parameter EFB to Users.
Pre requisite is You should have Maintained Purchase Info Record.
