SAP Error Message - Details

• Message type: E = Error

• Message class: BRAIN -

• Message number: 459

• Message text: Only "Equal To" and "Not Equal To" selections are permitted for char. &1

What causes this issue?

Characteristic &V1& is sorted using the external format, which is
different to the internal format. Selections are made using the internal
format. Selections that do not check to identify whether values are
equal or not equal (such as interval selections or "contains pattern"
selections) therefore do not generally return the required result.
The selection for characteristic &V1& is in query element &V2&.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Try to reformulate the selection. If you have used a selection option
variable for which the user can enter multiple single values only, use a
variable that represents <ZK>multiple values</>.

• What is the cause and solution for SAP error message BRAIN459 - Only "Equal To" and "Not Equal To" selections are permitted for char. &1 ?

  The SAP error message BRAIN459 indicates that in a certain context (usually in a query or report), only "Equal To" and "Not Equal To" selections are allowed for a character field (denoted by &1). This typically occurs in SAP BW (Business Warehouse) or SAP BI (Business Intelligence) environments when you are trying to filter or select data based on a character field using operators that are not permitted.
  Cause:
  
  Field Type Restriction: The character field you are trying to filter is restricted to only allow equality checks. This is common for fields that are not designed to support range selections or other comparison operators.
  Query Design: The query or report you are working with may have been designed with specific constraints on how data can be filtered, particularly for character fields.
  Data Model Limitations: The underlying data model may impose restrictions on how certain fields can be queried, especially if they are defined as attributes or characteristics.
  
  Solution:
  
  Change the Selection Operator: Modify your selection criteria to use only "Equal To" (=) or "Not Equal To" (<>). For example, instead of trying to use "Greater Than" or "Less Than", stick to equality checks.
  Review Query Design: If you have access to the query designer, review the settings for the query to ensure that the character field is being used correctly. You may need to adjust the query to accommodate the limitations of the field.
  Consult Documentation: Check the SAP documentation or help resources for the specific field you are working with to understand its limitations and intended use.
  Contact Support: If you are unsure about the restrictions or how to proceed, consider reaching out to your SAP support team or consulting with a BW/BI expert.
  
  Related Information:
  
  SAP BW/BI Documentation: Look for specific documentation related to query design and field types in SAP BW/BI.
  Field Properties: Check the properties of the character field in the data model to understand its constraints.
  SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.
  
  By adhering to the allowed selection operators and understanding the limitations of the character fields in your queries, you should be able to resolve the BRAIN459 error effectively.
