Hi ,
For this you need to pass the LOP day's to custom wage type and that you can call in your PCR.
Create a custom wage type and include that wage type in the V_T 554C table that absence valuation rule. Once you will add this wage type in the absence type valuation rule then it will come to IT table with details no of day's LOP during that payroll period which you have maintained in IT2001.
Based upon the PC08 this wage type amount will pass to RT table.
In the PE51 pay slip you can call this wage type and add accordingly.
