• What is the cause and solution for SAP error message /IWBEP/CM_EQ022 - Filter on Text Fields is not supported ?

  The SAP error message /IWBEP/CM_EQ022 Filter on Text Fields is not supported typically occurs in the context of OData services when a filter is applied to a text field that is not supported by the underlying data model or the OData service implementation. This can happen when you try to filter on fields that are defined as text or string types in the data model, but the OData service does not support filtering on those fields.
  Cause:
  
  Data Model Limitation: The underlying data model may not support filtering on text fields due to the way the data is structured or the limitations of the database.
  OData Service Implementation: The OData service may not have been designed to handle filters on text fields. This could be due to performance considerations or the nature of the data.
  Incorrect Filter Syntax: The filter syntax used in the OData query may be incorrect or not aligned with the expected format for text fields.
  
  Solution:
  
  Check OData Service Documentation: Review the documentation for the OData service to understand which fields can be filtered and the expected syntax for filtering.
  Modify the Query: If filtering on the text field is not supported, consider modifying your query to filter on other fields that are supported. You may need to retrieve the data without filtering and then apply filtering logic on the client side.
  Use Alternative Fields: If possible, use alternative fields that can be filtered. For example, if you are trying to filter on a description field, see if there is a corresponding ID or code field that can be used instead.
  Enhance OData Service: If you have control over the OData service implementation, consider enhancing it to support filtering on text fields if it makes sense for your use case. This may involve modifying the service's backend logic or data model.
  Consult SAP Notes: Check for any relevant SAP Notes or updates that may address this issue or provide additional guidance.
  
  Related Information:
  
  OData Protocol: Understanding the OData protocol and its limitations can help in designing queries that work within the constraints of the service.
  SAP Gateway: If you are using SAP Gateway, familiarize yourself with the capabilities and limitations of the Gateway framework regarding OData services.
  Performance Considerations: Filtering on text fields can lead to performance issues, especially with large datasets. It's important to consider the implications of such filters on system performance.
  
  If the issue persists after trying the above solutions, it may be beneficial to reach out to SAP support or consult with a technical expert familiar with your specific SAP environment and OData services.
