How To Fix DO339 - Data element defined recursively

SAP Error Message - Details

• Message type: E = Error

• Message class: DO - Dictionary: Mass activation of domains and data elements

• Message number: 339

• Message text: Data element defined recursively

What causes this issue?

A <DS:TX.DDDOK_DTEL>data element</> must not be defined recursively -
that is, it must not <DS:TX.DDDOC_REFTYPE>reference</> any other
<DS:TX.DDDOC_DDTYP>type</> (data element, structure, table type) that,
in turn, directly or indirectly references or uses the data element.
You have defined the data element recursively.

System Response

Remove this recursivity in the definition of the data element. For
example, you can reference another type that does not directly or
indirectly reference or use the data element.

How to fix this error?

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 DO339 - Data element defined recursively ?

  The SAP error message DO339, which states "Data element defined recursively," typically occurs when there is a recursive definition in the data element or structure definition in the ABAP Dictionary. This means that a data element is defined in such a way that it refers back to itself, either directly or indirectly, which creates a loop that the system cannot resolve.
  Cause:
  
  Recursive Definition: The most common cause is that a data element or structure is defined in a way that it references itself. For example, if a structure contains a field that is of the same structure type, it leads to a recursive definition.
  Incorrect Data Element Usage: Sometimes, a data element might be incorrectly used in a table or structure definition, leading to this error.
  Copy-Paste Errors: If a developer copies and pastes definitions without properly adjusting references, it can lead to recursive definitions.
  
  Solution:
  
  Review Data Element Definitions: Check the definition of the data element that is causing the error. Ensure that it does not reference itself directly or indirectly.
  Modify Structure Definitions: If the error is in a structure, modify the structure to remove the recursive reference. Ensure that fields in the structure do not point back to the structure itself.
  Use Alternative Data Types: If you need to represent hierarchical data, consider using alternative data types or structures that do not create recursion.
  Check for Indirect References: Sometimes, the recursion might not be direct. Check if the data element is part of another structure that eventually leads back to the original data element.
  Consult Documentation: If you are unsure about the definitions, refer to SAP documentation or guidelines on data element and structure definitions.
  
  Related Information:
  
  ABAP Dictionary: Understanding how to properly define data elements and structures in the ABAP Dictionary is crucial to avoid such errors.
  Data Element: A data element defines the type of data that can be stored in a field, including its attributes and domain.
  Structures: Structures are used to group related fields together. They should be defined carefully to avoid recursive definitions.
  SAP Notes: Check SAP Notes for any specific guidance or patches related to this error, as there may be updates or best practices provided by SAP.
