Hi,
This can be achieved through Time evaluation using PCR. Let me know EL/HPL quotas are generated through Time evaluation ?
If yes you dont require any user exit /Badi or workflow . Just a few PCR are required to accommodate you requirement .
Else if you say these quotas are generating from RPTQTA00 you can use BADI (HRPA00INFTY) to put a Prefix and suffix while applying EL/HPL it will check for previous 2 days is staurday and sunday if yes then it is must that employee have apply leave on saturday sunday and monday .
