• Message class: QP - Message IDs for function module group QPAA

• Message number: 449

• Message text: There is no long-term characteristic used in the formula

What causes this issue?

The calculated characteristic is defined as a long-term characteristic.
The formula, however, does not contain a reference to a long-term
characteristic so that the calculated characteristic can also be
completed, after the short-term characteristics have been recorded.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check whether the calculated characteristic must be defined as a
long-term characteristic.

• What is the cause and solution for SAP error message QP449 - There is no long-term characteristic used in the formula ?

  The SAP error message QP449 ("There is no long-term characteristic used in the formula") typically occurs in the context of Quality Management (QM) when working with quality control plans and inspection characteristics. This error indicates that the system is expecting a long-term characteristic to be defined in the formula, but it cannot find one.
  Cause:
  
  Missing Long-Term Characteristic: The formula defined in the quality control plan is expected to reference a long-term characteristic, but none has been specified.
  Incorrect Formula Configuration: The formula may be incorrectly set up or may not be aligned with the expected characteristics.
  Data Inconsistency: There may be inconsistencies in the data or configuration settings related to the quality control plan or inspection characteristics.
  
  Solution:
  
  Check the Formula: Review the formula used in the quality control plan. Ensure that it includes a long-term characteristic. If it does not, you may need to modify the formula to include one.
  Define Long-Term Characteristics: If long-term characteristics are not defined, you will need to create them in the system. This can be done through the relevant configuration settings in the QM module.
  Review Characteristic Assignment: Ensure that the characteristics assigned to the inspection plan are correctly set up and that they include long-term characteristics.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on setting up long-term characteristics and formulas in quality control plans.
  Testing: After making changes, test the quality control plan to ensure that the error no longer occurs.
  
  Related Information:
  
  Quality Control Plans: These are used to define how quality inspections are to be carried out, including the characteristics to be measured and the formulas for evaluation.
  Inspection Characteristics: These are specific attributes or properties of a product that are measured during quality inspections.
  Long-Term Characteristics: These are characteristics that are expected to be stable over time and are used for long-term quality assessments.
  
  If the issue persists after following these steps, it may be beneficial to consult with an SAP QM expert or reach out to SAP support for further assistance.
