Somebody please throw some light on creating a substitution or validation to throw an error message or prevent a user to change tax code in MIRO for a PO.
In case it can be done, some clues are greatly appreciated.

Please create a validation in GGB0 and assign the same in OB28
create substitution in GGB1 and assign the same in OBBH.
If there is any contradiction between these two, validation prevails.
Thank for the reply. Can you tell me what are the parameters to be taken? How can I indicate the tax code as non editable? Kindly guide.
