  The SAP error message UGMD8105 indicates that there is an issue with data type conversion in your SAP system. Specifically, it means that the system is trying to convert a value from one data type to another, but the two data types are incompatible. This can occur in various scenarios, such as during data entry, data processing, or when executing certain transactions.
  Cause
  The error can be caused by several factors, including:
  
  Incompatible Data Types: The fields involved in the operation have different data types that cannot be converted. For example, trying to assign a string value to a numeric field.

  To resolve the UGMD8105 error, you can take the following steps:

  Data Validation: Validate the data being entered or processed to ensure it adheres to the expected formats. For example, ensure that numeric fields do not contain non-numeric characters.
  Debugging: If the error occurs in a custom ABAP program, use the debugger to trace the execution and identify where the incompatible data types are being used.
  Consult Documentation: Refer to SAP documentation or help resources for specific details about the fields and their expected data types.
