How To Fix QE615 - No standard deviation available for the measured values

QE615 - Overview

• Message type: E = Error

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

• Message number: 615

• Message text: No standard deviation available for the measured values

What causes this issue?

The standard deviation of the valid measured values for the sample or
the inspection characteristic is missing. However, the procedure you
selected needs this value for the share estimate.

System Response

The shares of units that are too small, too large, or nonconforming
were not calculated.

How to fix this error?

Record valid measured values and enter the missing value, or it is
calculated internally by the system.

• What is the cause and solution for SAP error message QE615 - No standard deviation available for the measured values ?

  The SAP error message QE615 ("No standard deviation available for the measured values") typically occurs in the context of quality management (QM) when dealing with inspection results. This error indicates that the system is unable to calculate the standard deviation for a set of measured values, which is often required for statistical quality control processes.
  Causes:
  
  Insufficient Data: The most common cause is that there are not enough measured values to calculate a standard deviation. Standard deviation requires at least two data points.
  Missing or Incorrect Data: If the measured values are missing, incorrect, or not properly recorded, the system cannot compute the standard deviation.
  Measurement Type: The measurement type may not support standard deviation calculations. For example, certain qualitative measurements may not have a standard deviation.
  
  Configuration Issues: There may be configuration issues in the quality management module that prevent the calculation of standard deviation.
  
  Solutions:
  
  Check Measured Values: Ensure that there are at least two
