Thank you sooooooooooooooooooooooooo much for your swift response and fully support.May I suggest to remove all my hiring persoonel action and Do New hiring with new staff ID.As you know, SAP should firstly add a new position into SAP org chart and this position will automatically escalate get the cost ctr of the father org ID’s . Then you can do next step personal hiring action, Now all is Err with all err manual operations.The best practice is using new Staff ID. Can you please kindly assign the mentor do it directly and this is not mentee can do as a test.If you want to test and study, kindly using SAP Q system and not current Production environment . Successfactors also has Q environment. Thanks again for your fully support. Looking forward my new Staff ID can be workable next Monday (Nov,8th,2021)
