Hi Vivek,
We are not running payroll in sap, nor we can we can write PCR.
The wage type should be stored only for reporting purpose, the requiremnet is as when an employee works on specfic shift schedule correspondingly allowance should be stored in IT 0014.
we just need to guide how to do that via dynamic action or a warning message after IT0007 to store IT0014, so that user dont miss to do the same.
Regards,
Rishitha
