Statistical Indicators

The Purchasing application uses three indicators for maintaining statistics:  delivery performance, price performance, and quality performance.

Delivery Performance

Counters are maintained for recording on-time, early and late releases.  The counters are maintained in the Quantity Control Program when the balance due of the release reaches zero (or, in the case of a decrease in quantity, when the balance due equals the release quantity).  The on-time delivery days tolerance (entered in the Purchasing System Defaults record on the Reference File) determines in which category--on-time, early, or late--each release falls.  For example, if the receipt date is greater than the dock date but not greater than the dock date plus the on-time delivery tolerance days, the release in recorded as being on-time.

Price Performance

Amounts are maintained for the received quantity at standard unit cost and the unit cost of the purchase order for standard costed warehouses and parts.  For moving average costed warehouses and parts, the volume at standard cost and the volume at unit cost are the same.

Receipt transactions in the Receipt Quantity Control conversation increment these two fields (or decrement them if the counted quantity is decreased).  If a quantity is rejected during quality control for scrap or return (without replacement), the volume at standard cost and the volume at unit cost fields are not affected.  If an over-shipment or return with replacement transaction is processed, the value at standard cost and volume at unit cost are decremented.

Quality Performance

Quantities are maintained for accepted, rework, rejected, and return classifications.  The rework quantity is a part of the accepted quantity.  Therefore, the quantity accepted as perfect is calculated as the accepted quantity minus the rework quantity.  The return quantity is a part of rejected quantity.  Therefore, the scrap quantity is calculated as the rejected quantity minus the return quantity.

During the Receipt Quantity Control conversation, if the receiving type of the line indicates that the quality control location will be used, the counted quantity is placed in the non-dispositioned quantity of the line.  Subsequent transactions during the Quality Control conversation decrease the non-dispositioned quantity and increase the accepted, rework, rejected, and return quantities as appropriate.

If the receiving type indicates that the quality control location will not be used, the counted quantity is considered accepted until decided otherwise; the entire amount increases the accepted quantity.  Subsequent transactions during the Quality Control conversation can then decrease the accepted quantity and increase the rework, rejected, and return quantities as appropriate.
