Partial Service Entry

Dear Friends,

Suppose a P O / WO for service is issued with one 1 qty and Po Value Rs 100.

Is it possible to make 3 service entries for single PO item on various dates and subsequently do miro against the same.

Currently the system make service entry for the full PO value even though partial services have been rendered for which partial miro and vendor payments have to be made.

Please advice and steps needed to perform the same.

Thanks and Regards

Mukesh
