Infotype 0210 - W4 Withholding

Question

We have a situation, where were using the payroll period start date for changes on infotype 210 and noticed on the second pay period, that it actually retro to the first pay.
For example our second payroll  date was Jan 22, 2010, period start date was 1/3/2010.
IT 210 tax change W-4 was dated 1/3/2010
The system made a retro change to the first payroll period for the second payroll. We noticed this was not the case before and always used the payroll period start date...
Can anyone tell me what triggers infotype 210 period start date or pay date? And also is there a setting in the config to control the different infotype(s) and/or document that points out how the infotype(s) work as regarding payroll period or pay date...
Thanks..

Hi Experts,
SAP advised us the following and the error was resolved.
Check the feature PAYS1 status If the status
is "saved". Please, perform the following:
The feature PAYS1 is a sub feature. Hence to generate the program for
the changed feature, it has to be regenerated with the main feature.
In this case the main feature is PAYSV.
To do so,
a) Execute transaction PE03.
b) Choose Tree Maintenance view from the menu.
c) Specify feature PAYSV, then choose Change.
d) Delete the node PAYS1 and re add it.
e) activate the Feature.
After this the field should be displayed in IT0210.
