Hi SAP HR,
You have to have all the leave types & quotas available against the employee type in the ERP system.
If you are currently using the ESS/MSS system then the same kind of configuration & set up has to be done for ESS/MSS the same has to be done for Mobile applocation where in the requests are routed to Mobile applications rather than to ESS/MSS.
Explore a bit on PTARQ T-code.
There are 3 differet SAP Mobile apps availbe , can i know which one you are using please??
Hope it help.
