  The SAP error message /IWBEP/EPM_BP025 Mandatory field &1 not passed typically occurs in the context of SAP Gateway or OData services when a mandatory field required for processing a request is not provided in the payload. This error is often encountered when working with Business Partner (BP) data in SAP systems.
  Cause:
  The error indicates that a required field (denoted by &1, which will be replaced by the actual field name in the error message) was not included in the request. This can happen due to several reasons:
  
  The client application did not send the mandatory field in the request payload.
  There may be a mismatch between the expected fields in the backend and what is being sent from the frontend.
  The OData service definition may have changed, and the client application is not updated accordingly.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify the Missing Field: Check the error message for the specific field name that is indicated by &1. This will tell you which mandatory field is missing.
  
  
  Review the OData Service: 
  
  Use transaction code /IWFND/MAINT_SERVICE to check the OData service and its metadata. 
  Look for the entity type and the properties defined as mandatory.
  
  
  
  Update the Client Request: 
  
  Ensure that the client application (e.g., Fiori app, custom application) is sending the required field in the request payload.
  If you are using a tool like Postman or a custom frontend, make sure to include the mandatory field in your request.
  
  
  
  Check Business Partner Configuration: 
  
  If the error is related to Business Partner data, ensure that the configuration for Business Partners in the backend is correct and that all mandatory fields are properly defined.
  
  
  
  Test the Changes: After making the necessary adjustments, test the request again to see if the error persists.
  
  
  Consult Documentation: If you are unsure about which fields are mandatory, refer to the SAP documentation or the OData service documentation for guidance on the required fields.
  
  
  Related Information:

  SAP Notes: Check for any relevant SAP Notes that might address known issues or provide additional guidance on the error.
  
  
  Debugging: If you have access to the backend, you can debug the OData service to see how the request is being processed and where it fails.
