Hello ,

We would like to change the legal entity of the employee,  With the same - hire date and whole data with the same start dates.
without transferred the employee in an update mode , or terminate his current work relationship - so they it change their status in the system. 

We tried the following scenarios in employee’s to move them from legal entity to another and didn’t manage :

1) transfer legal entities -by quick actions- this opened a new record with update mode for the work relationship.
