August 2008 Application Support Updates

2. Background
The AQ Process is an annual series of events which culminates in the recalculation of the annual quantity for all NDM and DM meter points, effective from 1st October. 
You will be aware from previous years that this is a major transactional event as it requires processing an extraordinary volume of data which, whilst we are starting now, will continue through September and into October. 
In order to mitigate and minimise any disruption to the file transactions, billing and the provision of data information services, an xoserve project team has been formed to manage the challenges and impacts, mitigate the risks and monitor progress to facilitate a successful conclusion. 
We have also carried out a number of enhancements to our systems not least the UK Link Technology refresh so that they are running at optimal processing capability during this year's AQ Review Process. 

3. Timeline There are 4 key phases: Phase 1 Meter AQ Calculation process
10th Mar – 21st Aug
Phase 2 Offer Review process / Supply Point Review process
23rd – 28th August
Phase 3 Setting The AQ Values
22nd – 28th September
Phase 4 Making the AQ Effective
1st – 3rd October – AQ Review Update UKL, IAD & ODS table rebuild (sp_portion)
2nd – 3rd October - IAD & ODS Catchup
4th – 8th October – Batch Catch Up

4. Phase 2 Impacts 23rd August – 26th August
There will be a delay of around 4 hours (from the timetabled routine) in sending the TRF files to Shippers on the 26th August 
IAD and ODS information will not reflect the latest data. This position will be resolved as part of the catch up plan.
We will be sending out more communications nearer the time which will identify any potential impacts that you may find on the other dates
