BAPI for setting holiday values

Hi,

I'm badly searching for a BAPI to set the holiday information from outside of SAP.

We have a very nice and higly accepted system to request and confirm holiday of an employee. Full workflow supported.

The only thing missing is to automatically set the accepted and confirmed holiday in SAP. Till now we have to enter the data again manually in SAP. 😔

Unfortunately I don't find anything.

Is there a already existing BAPI?
