Dear All,
I have solved the issues .
By following steps :
1. HRUSER Tcode ( Create ESS user and assign it to the employee master 105 info type )
1.2 : Assign necessary ESS Roles to the ESS User id created.
2. Make sure in 105 infotype Field USERID should be fill by respective SAP User id .
3. Implement 1875792 - ESS LEA: Dump in the leave request.
4. Congifure ESS Self Service in ERP backend system Correctly.
Thanks and Regards
Raheem
