Inside Purchase Order when clicked on Receive Product, a quality check is performed for a product with multiple quantities wherein lot/serial no. is allocated for each item.

E.g. Product Lamp is ordered in quantities of 4 then 4 different lot/serial no. are allocated and all 4 quantities go through a quality check.

Post completing the quality check, Validate option is displayed, on click of it, an Access Error is displayed saying :

"You are not allowed to create 'Lot/Serial' (stock.lot) records. 
No group currently allows this operation.
Contact your administrator to request access if necessary."

Kindly help me in resolving this Error.
