Adjust Dates in CRT

We are on version ECC6.

After the first payroll of February had been run, Payroll decided that they wanted to change our pay date from 3/5 to 2/29. I changed the payroll dates, changed the posting dates, etc., per their request. It seems that some employees on leave w/out pay have incorrect accumulation dates for their wage types in their payroll results. Is there a way to update those dates? It seems to only impact those employees who have no earnings on the 3rd payroll of the month. I have run program RPUCRT00, but this did not update the end dates for these employees.

In the CRT, the end date for wage type /101 shows 2/28/2012, but it should reflect the pay date 2/29/2012. Is there a way to adjust this date for this group of employees? Active employees who received pay on this 3rd pay date have the correct dates, so I don't think the issue is related to any dates in tables being incorrect or missed.

Thanks in advance for assistance!!
