Position not getting updated in PPOME

Hi All,

I am running an org reassignment action in which I am changing the position of the employee within the same Org unit. During me Org reassignment action, I input the new position ID to which the employee should be assigned, save the record and move forward.

Next is IT0001 infotype - the old position gets delimited as per the Org reassignment action date.

But, the employee is not getting automatically assigned in OM to the new position. I checked the inetgration switches as well.

PLOGI ORGA = X

PLOGI PLOGI = 01

PLOGI PRELI = 99999999

PPVAC PPVAC = 1

I am running these actions with retro dates.

Also, in OM, two records are getting created as shown in the screen shot.

16.12.2014 is the account assignment date in PPOME, which defaults to the date on which the position was created. I have changed the validity date of the position via PP01 to 01.01.1900. But I have noticed that an OM record gets created based on the account assignment date.

Is there a way to change this date as well??

Please suggest which link is missing.

Regards

Simran
