How To Fix QE717 - Control limits for track &1 could not be calculated

QE717 - Overview

• Message type: E = Error

• Message class: QE - RM-QSS Fehlertexte zur Ergebniserfassung

• Message number: 717

• Message text: Control limits for track &1 could not be calculated

What causes this issue?

The control limits for track &V1& on the control chart cannot be
calculated with the existing data.

System Response

The function was not carried out.

How to fix this error?

The procedure depends on the type of track and the type of inspection
characteristic. The following options are available:
In the case of an average value track, the standard deviations of the
samples are required to calculate the limits.
In the case of <ZH>summarized recording</>, you can enter these in the
single screen for the characteristic.
In the case of <ZH>classified recording</> or <ZH>recording of
individual values</>, the standard deviation is only determined
automatically during the valuation. In order to initiate the
calculation before the valuation is performed, call the function for
recording the statistical moments.
In the case of an average value track for an acceptance chart, if the
dispersion is large or the tolerance range is small, then the value
for the upper control limit can sometimes be less than that of the
lower control limit.
If this happens, then you should repeat the calculation at a later
date,when the dispersion has decreased.
Individual algorithms can often require a certain minimum number of
inspection results before a calculation is possible.
The exact requirements depend on the procedure stored for the track in
the Customizing application.

• What is the cause and solution for SAP error message QE717 - Control limits for track &1 could not be calculated ?

  The SAP error message QE717, which states "Control limits for track &1 could not be calculated," typically occurs in the context of quality management, particularly when dealing with control charts in SAP Quality Management (QM). This error indicates that the system was unable to compute the control limits for a specific track (or control chart) due to various reasons.
  Causes:
  
  
  Insufficient Data: The most common reason for this error is that there is not enough data available for the calculation of control limits. Control limits require a certain amount of historical data to be calculated accurately.
  
  
  Incorrect Configuration: The control chart or the associated settings may not be configured correctly. This includes settings related to the type of control chart being used or the parameters defined for the quality characteristic.
  
  
  Missing Master Data: Required master data, such as characteristics or specifications, may be missing or incorrectly defined.
  
  
  Statistical Parameters: The statistical parameters required for the
