PCR to compare ANZHL ( number/unit) Field on IT0014

Hi All,

I need to compare the - Number/unit field  of two wagetype records stored on IT0014.

These 2 wagetype are used to store Election % and Max % per staff member on IT0014.

The PCR needs to compare the Election % with Max Election % and give an error if Election % is greater than Election %.
Please let me know the function or operation which can be used in a PCR to compare the ANZHL field  between  wage types.

Thanks,

Shilpa
