OSS note 1606106

Hi all we are in discussion to apply OSS note 1606106 to switch the error message to a warning. After implementing this note can we still have the choice to apply warning message for some entities and error message for other?

We have several company codes which are using MLAC and I would like to know if we can assign only warning for some comapny codes (or plant) and let a error message for other? Thanks Christelle
