How To Fix BRAIN077 - You cannot change variable &1 for charact. &2 during query navigation

SAP Error Message - Details

• Message type: E = Error

• Message class: BRAIN -

• Message number: 077

• Message text: You cannot change variable &1 for charact. &2 during query navigation

What causes this issue?

The <ZK>Can be changed in query navigation</> property has been set for
variable &V1&, characteristic &V2&. However, the variable is used in the
query in such a way, that the system is unable to apply this
change-option.
This can, for example, occur under the following conditions:
Characteristic &V2& is filtered by additional restrictions (the
restrictions must be joined using an OR-connection)
A second characteristic, which is restricted by a variable, is
compounded to charcteristic &V2&.
Variable &V1& is a hierarchy node variable, but the hierarchy has not
been determined uniquely.
A variable can be changed during query navigation only if it is used
exclusively in a drilldown-characteristic, and there are no further
restrictions to the characteristic other than this variable. There must
be no additional characteristics with variables compounded to the
characteristic you are working with. For variables for hierarchy nodes,
the hierarchy must be determined uniquely and agree with the set
display hierarchy.
Also, if the characteristic value is moved, for example (&V1& - 1), the
variable is no longer able to be changed when navigating queries.

System Response

The entry <TK>&V1&</><ZK> Can be changed during query navigation</> is
not applied.

• What is the cause and solution for SAP error message BRAIN077 - You cannot change variable &1 for charact. &2 during query navigation ?

  The SAP error message BRAIN077 indicates that you are trying to change a variable in a query that is not allowed during query navigation. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when working with queries in BEx (Business Explorer) Analyzer or similar tools.
  Cause:
  The error arises when:
  
  You attempt to change a variable that is defined as a characteristic in a query while navigating through the results.
  The variable is set to be non-changeable during query execution, meaning it is locked for modification to maintain the integrity of the data being analyzed.
  The variable might be defined with certain properties that restrict its modification during query execution.
  
  Solution:
  To resolve the BRAIN077 error, consider the following steps:
  
  
  Check Variable Properties:
  
  Go to the query definition in the BEx Query Designer.
  Check the properties of the variable (characteristic) that is causing the issue. Ensure that it is set to allow changes if you want to modify it during navigation.
  
  
  
  Modify Query Settings:
  
  If the variable is intended to be changeable, you may need to adjust the settings in the query definition to allow for changes during navigation.
  Look for options related to "Allow Change" or "Input Ready" in the variable settings.
  
  
  
  Use Filters Instead:
  
  If changing the variable is not allowed, consider using filters or other navigation options to achieve the desired results without modifying the variable.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for specific guidance on handling variables in queries, as there may be additional settings or best practices to follow.
  
  
  
  Check User Authorizations:
  
  Ensure that you have the necessary authorizations to change variables in the query. Sometimes, restrictions can be due to user roles and permissions.
