• What is the cause and solution for SAP error message BRAIN_SUP023 - The default value for variable &1[&2] must not be '#' ?

  The SAP error message BRAIN_SUP023 indicates that there is an issue with a variable in a query or report where the default value is set to '#'. This typically occurs in the context of SAP Business Intelligence (BI) or SAP BW (Business Warehouse) when working with queries in BEx (Business Explorer) or similar reporting tools.
  Cause:
  The error arises because the default value for a variable is set to '#', which is not a valid default value. In SAP BW, '#' is often used to represent a "no selection" or "all values" option, but it cannot be used as a default value for a variable. This can happen if:
  
  The variable is incorrectly configured in the query definition.
  The variable is expected to have a specific value or range, but it has been set to an invalid placeholder.
  
  Solution:
  To resolve this error, you need to check and modify the variable settings in the query or report. Here are the steps to do so:

  Check Default Value Settings:

  Ensure that the default value is set to a valid value. You can set it to a specific value, or if you want to allow for no selection, consider using a different approach (like setting it to a range or using a selection option).
