• What is the cause and solution for SAP error message DO371 - No domain or data type was defined ?

  The SAP error message DO371 ("No domain or data type was defined") typically occurs when there is an issue with the definition of a data element or field in the ABAP Dictionary. This error indicates that the system cannot find a valid domain or data type associated with a particular field or data element.
