Error: Quantity Restriction Exceeded for Item

Hi,

We are performing Item Reclassification transaction for an Item with "From"

Which is setup as Serial Number Not Required & Lot Process Type as 7 - serial number assigned manually but quantity should not exceed one.

So, We have 1 quantity for the location Lot of this item, when we attempt to do a reclassification for this "FROM" Location Lot, we are getting the above error.

This is coming up for only this Item Location Lot combination but not coming up for any other .

Requesting your help on thos
