I have a special case.
If i try to update a vacancy in iRecruitment i get the error:
The mandatory argument object_version_number value cannot be null Cause: The mandatory argument object_version_number has either not been specified or has been explicitly set to null in the API per_raa_shd.lck. Action: Either specify a value for the object_version_number argument which is not null or contact your local support representative.
Question: How can i change this vaue without using any program?. It is not by all other vacancies the case.
