Hi,
For Make It14 wage type into the split then you can do in the below way.
Make a Custom specification like Z for PC47 for all the wage types for IT14 in V_512W_D.
Then you need to modify X011 PCR to your custom PCR and need to add the below few line in the PCR.
Under the Operation VWTCL 47 add the another sub level as Z and add the below section.
