Service cost to be included into Material value.

Dear Expert,

1. Purchase order has been created for "XXX" material - Value of 1000 - Quantity 10, GRN & Invoice has been booked.

Now my material valuation price is 1000 * 10 = 10000

2. Service PO has been raised to make alteration in same "XXX" material, the cost incurred has to be booked for that particular Material "XXX" only.

Two vendors are different.

Kindly advise

Regards,

Mohan
