HR infotype operation -inserting through webservice

Hi ,

I am trying to create a new entry in infotype 2001 for absences.

The FM is being called indirectly from sharepoint through a web service.

I have performed ENQUEUE ,DEQUEUE before and after calling the HR_INFOTYPE_OPERATION FM.

The FM executes fine, without any error messages.

But no data is created. Everything works fine when tested from sap itself.It fails only when calling from sharepoint.

i have already tried commit work and bapi_transaction_Commit. Doesnt help.

Is there any limitation when calling from external webservice?
