Modify Entries in DZL

Hi,

I have a scenario where in Time Pairs are to be converted to number of days instead of number of hours.

Function GMT is processing TIP (time pairs) and is creating wagetypes in DZL with number of hours in number field wherein i need number of days in number field. Each day has 12 hrs.

I am planning to write a PCR to divide the number of hours field by 12 to arrive at number of days. For this input for my rule should be DZL. What is the function that I need to use to modify entries in DZL ?

Any help will be greatly appreciated.

Thanks !
