Reconciliation Scenario 8

Diagram of reconciliation scenario 8

Opening balances (as at the start of the month):

  1. 1000 t
  2. 0 t

Transactions:

  1. 20th of the month, 300 t, Process flow PF1
  2. 21st of the month, 500 t, Process flow PF2

Closing balances (as at the end of the month):

  1. 200 t
  2. 800 t

Run a reconciliation on location B, of type Factorise. Change closing balance of stockpile 2 to 840 t. This introduces a discrepancy of 40 t which needs to be factored amongst the incoming transactions.

First the contributing tonnage factors for each process flow are calculated:

Factor = (Total transaction tonnes of process flows into product ) * (Process flow weighting for product)

Therefore, for PF1: 300 t * 60% = 180 t, and for PF2: 500 t * 40% = 200 t, a total of 380 t.

Then calculate the weighting for each process flow:

Weighting = (Factor for the process flow) / (Total of all factors for the product)

Therefore, for PF1: 180 t / 380 t, and for PF2: 200 t / 380 t

The new transaction tonnes are then calculated using these weightings:

New tonnes = Old tonnes + Discrepancy * Weighting for process flow

Therefore, new tonnes for Transaction 1 = 300 t + 400 t * 180 t / 380 t = 318.947 t,
and new tonnes for Transaction 2 = 500 t + 40 t * 200 t / 380 t = 521.053 t

After commit, the expected results are:

  • Survey of stockpile 2 of 840 t (with reason code Recon) at the end of the month.
  • Total adjustment for location B: 0 t.
  • Total adjustment for product Product 1 in location B: 0 t.
  • Transaction 1 has tonnage changed to 318.947 t. (The old tonnage of 300 t is stored in the BulkTransactionExt table, in the field Double5.)
  • Transaction 2 has tonnage changed to 521.053 t. (The old tonnage of 500 t is stored in the BulkTransactionExt table, in the field Double5.)
