How to Delete Collected Data from Predator MDC

You can delete collected data for a specific machine, all data for all machine up to a specific date, or delete a machine and all of its data. 

Requirements

  1. Predator MDC Administrator or Predator MDC Enterprise Administrator
  2. User account with permission to Delete Collected Data

Delete selected machine and all its data

This is used when you want to delete a machine that is no longer in use or does not need to be in the Predator MDC system
  1. Go to Administrator -> Delete Collected Data...
  2. Select Delete selected machine and all its data
  3. Select the machine using the filter below, click OK
  4. A warning will appear asking for confirmation, click Yes
  5. Depending on how much data has been collected, it will complete within a few minutes

Delete all data for specific machine

This is used when you want to delete only the data for a machine, but keep the machine itself in Predator MDC. Typically used to delete erroneous data or repurposed machines
  1. Go to Administrator -> Delete Collected Data...
  2. Select Delete all data for specific machine
  3. Select the machine using the filter below, click OK
  4. A warning will appear asking for confirmation, click Yes
  5. Depending on how much data has been collected, it will complete within a few minutes

Delete all data for all machines up to a specific date

This will delete data up to a specific date. For example, you want to delete all data prior to the year 2020, the Start Date would be 12/31/2019, this will keep all data in 2020, but delete data from 2019 and older
  1. Go to Administrator -> Delete Collected Data...
  2. Select Delete all data for all machines up to specific date
  3. Select State Date
  4. A warning will appear asking for confirmation, click Yes
  5. Depending on how much data has been collected, it will complete within a few minutes

Troubleshooting

  1. When trying to delete a machine and all of its data, "The DELETE statement conflicted with the REFERENCE constraint..." appears. This usually means there is data that used this machine as a reference which means it cannot delete the machine. Try deleting only the data for the specific machine, then retry deleting the machine. If this fails, send a screenshot of the error to support@shopfloorautomations.com. We will likely need access to your SQL server to find a solution.
