authorisation for buyers
our requirement is that one particular user should not change the net rate of one particular type of purchase Order. For this we have defined a new field selection group and assigned this field selection group to po document type. Without doing any authorisation configuration, with this field selection group, the net rate at item over view of PO is not changeable. But it is changeable at item detail level.
For this iam planning to configure "define authorisations for buyers'. I want create one authorisation group with display authorisation for this particular field selection group. When i configure this net rate is not changeble for any document type. It is not considering the field selection group assgined in "define authorisation for buyers" configuration.
is it possible to control this for only one particular document type?
