• What is the cause and solution for SAP error message /UI2/PAGE052 - Only operator "EQ" without any wildcards supported for filter ?

  The SAP error message /UI2/PAGE052 Only operator "EQ" without any wildcards supported for filter typically occurs in the context of SAP Fiori applications or SAP UI5 applications when a filter is applied to a data set. This error indicates that the filter operation being attempted is not supported due to the use of operators or wildcards that are not allowed in the context of the specific data source or service.
  Cause:
  
  Unsupported Filter Operator: The error arises when a filter is applied using operators other than "EQ" (equals). For example, using operators like "NE" (not equal), "GT" (greater than), "LT" (less than), or wildcards (like * or %) is not supported.
  Data Source Limitations: The underlying OData service or data model may only support equality checks for filtering, which is common in certain scenarios where performance or data integrity is a concern.
  Incorrect Filter Syntax: The filter syntax may be incorrectly formed, leading to the system not recognizing the intended operation.
  
  Solution:
  
  
  Use Only "EQ" Operator: Modify the filter criteria to use only the "EQ" operator. Ensure that the filter is checking for equality without any wildcards or other operators.
  
  Example: Instead of using fieldName eq 'value*', use fieldName eq 'value'.
  
  
  
  Check OData Service Documentation: Review the documentation for the OData service you are using to understand the supported filter operations and any limitations.
  
  
  Adjust UI Logic: If you are developing or customizing the UI, ensure that the logic for applying filters adheres to the constraints of the OData service. This may involve modifying the code to prevent unsupported filter operations from being executed.
  
  
  Debugging: If you are unsure where the filter is being applied, use debugging tools to trace the filter parameters being sent to the OData service. This can help identify the exact point where the unsupported operation is being invoked.
