MM GR quantity

Goods receipt quantity exceeds open purchase order quantity

MIGO warns or blocks a goods receipt because the receipt would exceed the remaining PO quantity/tolerance.

Likely root causes

  1. Posted GR quantity plus current receipt exceeds ordered quantity.
  2. Over-delivery tolerance is zero or too low for the valid business scenario.
  3. A previous GR/reversal was posted against the wrong PO item.

What to inspect

  1. PO ordered quantity and delivery tolerances.
  2. PO history including GRs and reversals.
  3. Current MIGO quantity and PO item reference.

Resolution path

  1. Correct the receipt quantity/reference if wrong.
  2. If the supplier legitimately delivered more and business accepts it, update the PO/tolerance through procurement approval.
  3. Correct erroneous historical GRs rather than increasing tolerance to mask them.
  4. Repost after open quantity is accurate.
