UK Payroll new tax code 1000L

Hello Friends:  
In UK Payroll new tax code 1000L for year 2014-April 06th.  I have updated in Constant table V_T511K effective April 06th 2014 but this code is not going to Ceridian interface(PU12).  I would like to know where we need to apply this new tax code?.  Is there any OSS Notes?. Any help is appreciated. Thanks in Advance
