Hi,
May be you have not assigned the workschedule rule in IT0007 based on PA, or PSA.
Kindly check the PA, PSA data and WSR in IT0007, so you have to chnage the work schdule rle in IT 0007 for your location. with effect from the date of orgreassignment.
Note: whats happening is, employee in deferent PA PSA grouping and workschdule what assigned now is deferent.change the work schdule rule in IT 0007 which is relavent to your new PA,PSA and run the time evaluation.
Regards,
