This PCR is proceed according to PC01 value.PCR X013 should followed by PCR X010.
Based on specification defined for processing class 01 in v_512w_d, PCR X010 generates wage types /001& /002 in RT table.
For these two technical wage types (/001 & /002) specification for processing class 01 must be 5.
Please go through documentation for X013 PCR. requirement slowly.
So what's your calculation ? Share the PCR input table details and output details with process log since I can see there have constant has been used in the rule so share the constant ZOTST from table V_T511K.
