• What is the cause and solution for SAP error message ISU_UMC_ODATA127 - Wildcard is not supported ?

  The SAP error message ISU_UMC_ODATA127 indicates that a wildcard character is being used in an OData query, which is not supported in the context of the operation you are trying to perform. This typically occurs when you are trying to filter or search for data using a wildcard (like * or %) in a field that does not allow it.
  Cause:
  
  Invalid Query Syntax: The OData query may contain a wildcard character in a filter expression where it is not allowed.
  Field Restrictions: Certain fields in the OData service may not support wildcard searches due to the way they are indexed or stored in the database.
  Data Type Mismatch: The field you are querying may not be of a type that supports wildcard searches (e.g., numeric fields).
  
  Solution:
  
  
  Remove Wildcards: Modify your OData query to remove any wildcard characters. Instead of using wildcards, use exact matches or other supported operators.
  For example, if your original query was:
  /EntitySet?$filter=FieldName eq 'Value*'
  Change it to:
  /EntitySet?$filter=FieldName eq 'Value'
  
  
  Use Supported Operators: If you need to perform a search that resembles a wildcard search, consider using other operators that are supported, such as startswith, endswith, or substringof if applicable.
  Example:
  /EntitySet?$filter=startswith(FieldName, 'Value')
  
  
  Check Documentation: Review the OData service documentation for the specific entity and field you are querying to understand the supported operations and any restrictions.
  
  
  Test Queries: Test your modified queries in a tool like Postman or directly in the SAP Gateway Client to ensure they return the expected results without errors.
