DT305 - Details

• The SAP error message DT305, which states "Foreign key &-& (No value table defined)," typically occurs when there is an attempt to use a foreign key relationship in a database table, but the corresponding value table is not defined in the Data Dictionary (DDIC). This can happen in various scenarios, such as when creating or modifying database tables or when working with data elements that are supposed to reference a value table.
  
  Cause:
  
  Missing Value Table: The primary cause of this error is that the foreign key field is referencing a data element that does not have an associated value table defined in the Data Dictionary.
  Incorrect Data Element Configuration: The data element used for the foreign key may not be properly configured to point to a valid value table.
  Inconsistent Table Definitions: There may be inconsistencies in the definitions of the tables involved, leading to the foreign key constraint being invalid.
