Only one entry can be set as default for a given object in one company. E.g. if there are two entries for object VENDOR in company 1, only one should be set as default. If one entry is already set as default and the user sets another entry for the same object in the same company as default, after clicking the ‘save’ button only the second entry will remain default (radio button behavior).
See the comments for the transaction /PACG/ECM_SAASG – the analogue logic is applied for purchasing organization dependent object.
If vendors for other companies are created the object "vendor" has to be assigned to the relevant purchasing organization
