  The SAP error message PP_ODATA_API_WKC000 typically indicates that there is an issue with filling a specific field during a change operation in the OData API related to Production Planning (PP). The message format suggests that it is trying to fill a field (represented by &1) for a specific object (represented by &2), but it is unable to do so.
  Cause
  The error can be caused by several factors, including:
  
  
  Field Restrictions: The field you are trying to fill may have restrictions or conditions that are not being met. For example, it could be a mandatory field that is not being provided or a field that is not allowed to be changed in the current context.
  
  
  Data Type Mismatch: The data being sent to the field may not match the expected data type or format. For instance, if the field expects a numeric value and a string is provided, this could trigger the error.
  
  
  Business Logic: There may be business logic or validation rules in place that prevent the field from being filled under certain conditions. This could be related to the status of the object being changed.
  
  
  Authorization Issues: The user or service account making the change may not have the necessary authorizations to modify the specified field.
  
  
  OData Service Configuration: There could be issues with the OData service configuration itself, such as missing or incorrectly defined entity types or properties.
  
  
  Solution
  To resolve the error, consider the following steps:
  
  
  Check Field Requirements: Review the documentation or configuration for the specific field (&1) to understand its requirements and restrictions. Ensure that you are providing all necessary data.
  
  
  Validate Input Data: Ensure that the data being sent to the API is in the correct format and matches the expected data types for the fields being modified.
  
  
  Review Business Logic: Check if there are any business rules or conditions that might prevent the field from being filled. This may involve reviewing the status of the object (&2) and ensuring it is in a state that allows changes.
  
  
  Authorization Check: Verify that the user or service account has the necessary permissions to modify the field in question.
  
  
  Debugging: If you have access to the backend, consider debugging the OData service to see where the error is being triggered. This can provide insights into what is going wrong.
