Add Value from IT15 onto Payslip (PE51)

Hi there,

I have a client that is switching away from using SAP's time management, and they are now using an external time management system, but still using SAP for payroll. They need to now stop pulling leave quotas from the clusters, and rather read custom wage types stored in info-type 15.

So, for example, to get the correct leave balance, they want to read info-type 15 for subtype "9BLE". How can I achieve this?

I have already tried to add table P0015 via PE51_CHECKTAB, but when I add the single fields in PE51 as below, it only ever prints a zero value...

Clik here to view.

How do I go about printing, as a single field, a specific subtype value from info-type 15?

Thanks
