System Response

Warning

How to fix this error?

If you set up a data transfer from an SAP report, ignore the warning.
During an external data transfer from a presentation server file, the
DDIC structure must consist of purely character-like fields of the C, N
or D type. Otherwise, this leads to termination due to Unicode errors.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message UC799 - The sender structure does not contain character-like fields ?

  The SAP error message UC799, which states "The sender structure does not contain character-like fields," typically occurs in the context of data transfer processes, such as when using the SAP Data Transfer Workbench or during data migration activities. This error indicates that the structure you are trying to use as a sender does not have any fields that are of a character-like data type (e.g., CHAR, STRING, etc.).
  Cause:
  
  Data Structure Definition: The sender structure defined in your data transfer process does not include any fields that are character-like. This could be due to the structure being defined with numeric or other non-character data types only.
  Incorrect Mapping: The mapping between the source and target structures may not be set up correctly, leading to the absence of character-like fields in the sender structure.
  Data Source Issues: If the data source (like a database table or a file) does not contain character-like fields, this error can occur.
  
  Solution:
  
  Check Structure Definition: Review the definition of the sender structure in the data transfer process. Ensure that it includes at least one character-like field. You may need to modify the structure to include such fields.
  Modify Mapping: If you are using a mapping tool, check the mapping configuration to ensure that character-like fields are correctly mapped from the source to the target.
  Data Source Verification: Verify the data source to ensure that it contains character-like fields. If it does not, you may need to adjust your data extraction or transformation logic to include such fields.
  Use a Different Structure: If the current structure is not suitable, consider using a different structure that includes character-like fields for your data transfer.
  
  Related Information:
