Pegging (business informatics)

from Wikipedia, the free encyclopedia

In MRP invoices (also MRP II or ERP ), pegging or cause of demand is the ability to see the origin of a demand that led to a triggered order.

The material planning function of classic MRP / MRP II / ERP systems adds up primary and secondary requirements according to parameterized specifications. As a result, the relationship between the production order and the sales order is lost - one component could be incorporated into products for different sales orders. In order to remain able to act with changes, the function of was Pegging (Engl. Pinning ) - in the jargon also drill down called - introduced with a dispatcher can find the job whose schedule, quantity or storage change to the change in the resulting secondary demand.

A distinction is made between fixed and dynamic pegging.

  • With fixed pegging, the assignment of a higher-level requirement to a lower-level requirement is retained during planning.
  • With dynamic pegging - depending on the planning situation - the assignment of higher-level requirements to lower-level requirements can change.

example

A component "A" is assembled from 2 parts "B" and 1 part "C".

For component "A" there is a requirement of 10 pieces and a second requirement of 20 pieces in the same week.

It follows that 60 parts B ((10 + 20) * 2) and 30 parts C (10 + 20) must be made in the previous week.

If one of the higher-level requirements changes, e.g. B. the order for 10 parts is reduced to 5), then the requirement "suddenly" shows 50 parts B and 25 parts C.

Pegging allows the dispatcher to see which order (i.e. the one for 10 or the one for 20 parts A) has changed.
