Each Settlement Run generates six different reports. All settlement reports are available to Trading Parties via Jaspersoft within CMOS and a user specific FTP site. In addition, MOSL also publishes Settlement Checker Reports and System Exception Reports, as seen below.

This report shows the charges per wholesale-retail pair based on aggregate numbers of Service Components. These values are used as the basis of payments between wholesalers and retailers.


This report gives a breakdown of charges by Supply Point (the point at which services are provided) for water and sewerage services.

This report gives a breakdown of charges by supply point for Trade Effluent services.

This report gives details of meter networks which arise when the volumes of water calculated for different supply points are interdependent.

For example the water volume associated with SPID 1 is dependent on the meter reads on the main meter M and on the sub-meter S (as the volume of water consumed by SPID 1 = M – S).

Read more about meter networks.


This report gives details of user exceptions which is where settlement calculations have been unable to complete due to data error by a Trading Party. 

Settlement Checker Reports are used to identify significant changes in values between specified Settlement Reports. There are three report types that are distributed to each wholesaler and retailer:

T1: Total Charge per Wholesaler/Retailer Pair

T2: SPID Level Charge Comparison

T3: Total SPID Count

For each new Settlement Run the following Settlement Runs are compared:

P1 (Current Month) – P1 (Previous Month)

R1 (Current Month) – R1 (Previous Month)

P1 (Available Month) – R1 (Available Month)

Rn+1 (Available Month) – Rn  (Available Month)

System Exception Reports detail the errors encountered by CMOS when attempting to calculate charges for SPIDs, where those errors are caused by CMOS validation issues.

Further details on System Exceptions, including examples, can be found in Appendix C.4 of CSD 0207: 'Charge Calculation, Allocation and Aggregation'.

System Exception Reports are published for each Trading Party. Both Settlement Checker and System Exception Reports are made available to Trading Parties via a user specific folder in the MOSL User forum. Further information regarding Settlement Reports can also be found in CSD 0201: Settlement timetable and reporting.
