How To Fix BRAIN261 - Characteristic &1 has a constant value (&2) and cannot be used

SAP Error Message - Details

• Message type: E = Error

• Message class: BRAIN -

• Message number: 261

• Message text: Characteristic &1 has a constant value (&2) and cannot be used

What causes this issue?

Characteristic &V1& is set as constant (COB_PRO-CHACONST = &V2&) and is
therefore no longer visible in the InfoProvider.

System Response

At runtime, characteristic &V1& is ignored and removed from the
drilldown.

How to fix this error?

The characteristic is used in the query to be executed even though it is
no longer visible in the InfoProvider. You can resolve the problem by
changing the query in the Query Designer. The system proposes an
appropriate solution to how the InfoObject that does not exist or is not
visible can be removed from the query. You must ensure that the query is
still defined meaningfully.

• What is the cause and solution for SAP error message BRAIN261 - Characteristic &1 has a constant value (&2) and cannot be used ?

  The SAP error message BRAIN261 indicates that a characteristic in your query has been assigned a constant value, which means it cannot be used in the context of the query you are trying to execute. This typically occurs in the context of SAP BW (Business Warehouse) queries, particularly when working with BEx (Business Explorer) queries or when defining variables.
  Cause:
  
  Constant Value Assignment: The characteristic in question has been assigned a constant value in the query definition. This means that it is fixed and cannot be changed or filtered dynamically during query execution.
  Query Design: The characteristic is being used in a way that requires it to be variable or dynamic, but it has been set to a constant value.
  Incorrect Query Logic: The logic of the query may be incorrectly set up, leading to the use of a characteristic that should be variable but is defined as constant.
  
  Solution:
  
  Review Query Definition: Go to the query designer and check the definition of the query. Look for the characteristic mentioned in the error message and see if it has been assigned a constant value.
  Remove Constant Assignment: If the characteristic is set to a constant value, consider removing this assignment or changing it to allow for dynamic filtering. This can usually be done by:
  
  Editing the properties of the characteristic in the query designer.
  Changing the filter settings to allow for variable input instead of a fixed value.
  
  
  Check for Variables: If you need to use a variable instead of a constant, ensure that you have defined a variable for that characteristic and that it is being used correctly in the query.
  Test the Query: After making changes, test the query to ensure that it runs without errors and returns the expected results.
