Displaying the Transfer Hierarchy for a Key Date 

Use

If you have defined transfer dependencies for measuring points and counters, you can display them with respect to time. Depending on the key date, you can display both historical and current transfer dependencies.

If a measurement document is entered for an historical reference time, the transfer of the measurement document is performed according to the historical transfer dependencies, even if the object structure has changed in the meantime.

In an airplane, an average of 2500 pieces of equipment are installed, each with three counters per piece of equipment. One measurement document is created per counter per day and transferred within the defined hierarchy. Sometimes, the case arises where the counter readings are equivalent to planned values that have to be recorded each time the airplane is used, because the actual values are not obtained until some time later. If the actual values that are obtained later deviate from the planned values, they must be updated accordingly. The transfer of these measurement documents that are entered subsequently is performed according to the historical transfer dependencies.

Displaying the Transfer Structure for a Key Date

  1. In the master record of the measuring point or counter, choose Extras ® Measurement reading transfer ® ...Structure.
  2. Enter the required key date. The key date can be either in the present or in the past.
  3. Choose Continue. The system displays the structure of the measurement reading transfer for the key date that you entered. The technical objects concerned are displayed with their measuring points or counters in the form of an object hierarchy. The measuring point or counter from which you called up the function is highlighted.
  4. If you want to change the key date, choose and enter the new key date.
  5. Choose Log, to display the results of the consistency check. Messages that are displayed for the log can also include information about deactivated measuring points or counters.

Displaying the History from the Perspective of the Measuring Point/Counter

  1. In the master record of the measuring point or counter, choose Extras ® Measurement reading transfer ® ...History.
  2. The system displays the transfer dependencies in the form of a time line. This time line usually corresponds to the usage list for the piece of equipment.
