• What is the cause and solution for SAP error message RS2HANA_VIEW172 - &1:Optional hier. var. with no default value. Query view not generated. ?

  The SAP error message RS2HANA_VIEW172 indicates that there is an issue with a query view in SAP BW/4HANA or SAP BW on HANA. Specifically, the error states that there is an optional hierarchical variable that does not have a default value, which prevents the query view from being generated.
  Cause:
  
  Optional Hierarchical Variable: The query contains an optional hierarchical variable that is not assigned a default value. This means that when the query is executed, the system does not know what value to use for this variable, leading to the failure in generating the query view.
  Query Design: The design of the query may not have accounted for the requirement of a default value for optional variables, which is necessary for the query to execute properly.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Assign a Default Value:
  
  Go to the query designer in SAP BW/4HANA.
  Locate the optional hierarchical variable that is causing the issue.
  Assign a default value to this variable. This can be done in the properties of the variable where you can specify a default value that will be used when the query is executed.
  
  
  
  Make the Variable Mandatory:
  
  If it is appropriate for your use case, consider changing the variable from optional to mandatory. This will require users to provide a value when executing the query, thus eliminating the need for a default value.
  
  
  
  Check Variable Settings:
  
  Review the settings of all variables in the query to ensure that they are configured correctly. This includes checking for any other optional variables that may also lack default values.
  
  
  
  Test the Query:
  
  After making the necessary changes, test the query to ensure that it generates correctly and that the error message no longer appears.
  
  
  
  Related Information:
  
  Hierarchical Variables: These are used in queries to allow users to select specific nodes from a hierarchy. They can be optional or mandatory based on the design of the query.

  SAP Notes and Documentation: Always check for relevant SAP Notes or documentation that may provide additional insights or updates related to this error message.
