In the case of a source inspection, the SAP system helps you calculate the right inspection start date. To define the inspection start date, it subtracts an inspection lead time from the expected delivery date. How does that work? From a technical perspective, no inspection lot for the source inspection is created when you post the goods receipt. Instead, the system checks the estimated delivery date in the purchase order and the inspection lead time maintained in the quality info record (procurement). It creates an inspection lot for goods receipt in which the inspection start date corresponds to the expected delivery date minus the inspection lead time. Then, before the goods receipt posts, you can execute the quality inspection results, record inspection results, or defects in the respective inspection lot.
Set the indicator Source inspection instead of GR inspection in the quality info record (procurement). This avoids the system creating another inspection lot after transporting the goods to your premise and posting the goods receipt for this purchase order. In addition, consider that, in this case, quality problems during transport cannot be detected. You do not execute a classical goods receipt inspection. If you want to create another inspection lot when posting the goods receipt, do not enable this indicator in the quality info record (procurement).
