How To Fix BRAIN255 - Variable &2 is ignored if no entries are made at runtime

SAP Error Message - Details

• Message type: E = Error

• Message class: BRAIN -

• Message number: 255

• Message text: Variable &2 is ignored if no entries are made at runtime

What causes this issue?

If no value is specified for an optional variable, the system assumes
there are no restrictions and displays all data.
However, variable &V2& for characteristic &V1& is used with additional
including conditions in the fixed filter. Therefore, no input for &V2&
is interpreted as though the condition does not exist.
If all including conditions for &V1& are optional variables, and no
entry is made for these variables, all data is displayed.

• What is the cause and solution for SAP error message BRAIN255 - Variable &2 is ignored if no entries are made at runtime ?

  The SAP error message BRAIN255 indicates that a variable in a query is being ignored because no entries were made at runtime. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when executing queries that involve variables.
  Cause:
  The error arises when a query is executed with a variable that has not been populated with any values at runtime. This can happen for several reasons:
  
  No Input Provided: The user did not provide any input for the variable when prompted.
  Default Values: The variable is set up without default values, and the user did not enter any values.
  Variable Settings: The variable may be configured to be mandatory, but the user did not fulfill this requirement.
  Data Source Issues: There may be issues with the data source that prevent the variable from being populated correctly.
  
  Solution:
  To resolve the BRAIN255 error, consider the following steps:
  
  
  Check Variable Settings:
  
  Go to the query definition in the Query Designer.
  Check the properties of the variable in question. Ensure that it is set up correctly, including default values if necessary.
  
  
  
  Provide Input:
  
  When executing the query, ensure that you provide the necessary input for the variable. If the variable is mandatory, it must be filled out.
  
  
  
  Default Values:
  
  If appropriate, set default values for the variable in the query definition. This can help avoid the error if users forget to input values.
  
  
  
  Review Query Execution:
  
  If the query is being executed through a report or dashboard, ensure that the interface allows users to input values for the variable.
  
  
  
  Check Data Source:
  
  Verify that the data source is functioning correctly and that there are no issues that might prevent the variable from being populated.
  
  
  
  Testing:
  
  Test the query with different inputs to ensure that it behaves as expected and that the variable is being recognized.
  
  
  
  Related Information:
  
  Variable Types: Understand the different types of variables (e.g., selection variables, text variables) and how they are used in queries.
  Query Designer: Familiarize yourself with the SAP Query Designer tool, as it is essential for creating and modifying queries.
  Documentation: Refer to SAP documentation for detailed information on variable handling and error messages in SAP BW/BI.
