Best Practice for Account Intravaluation Unit Transfer checkbox on Cost Profiles

Summary: We are trying to determine the repercussions to inventory, costing, and the general ledger accounts if we remove the check from the Account Intravaluation Unit Transfer checkbox on our cost profiles. What is considered best practice for this profile option and why would our implementation partner have recommended we should select it?

Content (please ensure you mask any confidential information): We recently enabled the auto pick function which has greatly increased the number of warnings we receive from the cost processor when running the end of month processes. The message is "The transfer receipt cannot be costed until the issue transaction is fully processed with sufficient on-hand quantity." Because these are just warnings they don't negatively impact EOM close but the substantial volume does increase the possibility of missing, and not resolving, a message that does have a negative impact.
