Hi Fayaz,
Employee master data can be replicated to SAP CRM either using PFAL from SAP ECC or executing a program HRALXSYNC in SAP CRM. There are some settings has to be done in SAP CRM and SAP ECC for this. Along with this IDOC settings need to be enabled on both side.
Table T77s0 has to be maintained.
Refer Replicate HR Org Model from SAP ECC into SAP CRM
Also there is sap note which tells step by step procedure.
Thanks
Ajay
