BAPI_PERSDATA_CHANGE leading to cx_hrpa_violated_precondition exception

Hi Experts,

My aim is to update employee data using RFCs. To achieve this, I'm trying to test BAPI_PERSDATA_CHANGE on an SAP ECC 6.0 IDES  instance (running on a remote Windows host). Unfortunately, this is leading to an exception.

I am successfully able to READ an employee's data using the BAPI: BAPI_EMPLOYEE_GETDATA.

The output of BAPI_EMPLOYEE_GETDATA is:

I know that I must call the following three BAPI's in order:

BAPI_EMPLOYEE_ENQUEUE

BAPI_PERSDATA_CHANGE

BAPI_EMPLOYEE_DEQUEUE

But running BAPI_PERSDATA_CHANGE using transaction SE37 with the following IMPORT parameters:

EMPLOYEENUMBER='72',

NOCOMMIT='X',

LOCKINDICATOR='<space character>',

OBJECTID='<space character>',

RECORDNUMBER='0',

VALIDITYBEGIN='19650908',

VALIDITYEND='99991231',

SUBTYPE='<space character>',

LASTNAME='Foosh'

Leads to this error:
