How To Fix SPRX072 - Item is part of recursion (see long text for additional information)

SAP Error Message - Details

• Message type: E = Error

• Message class: SPRX - Proxy Generation

• Message number: 072

• Message text: Item is part of recursion (see long text for additional information)

What causes this issue?

The type contains recursions. This means that a type references itself
(possibly indirectly).
Example:
A packing unit is described by its length, width, height, and content.
The content can also consist of packing units.
<complexType name="PackingUnit">
<sequence>
<element name="length" type="int"/>
<element name="width" type="int"/>
<element name="height" type="int"/>
<element name="content" type="PackingUnit"
maxOccurs="unbounded"/>
</sequence>
</complexType>
In ABAP, recursively defined structures are not possible.
Currently, the only solution is to replace a recursive reference by a
reference to the data element XSDANY, so that the structure looks like
this:
Dictionary structure PACKING_UNIT
Field LENGTH TYPE INT4
Field WIDTH TYPE INT4
Field HEIGHT TYPE INT4
Field CONTENT TYPE PACKING_UNIT_CONTENT_TAB
Dictionary table type PACKING_UNIT_CONTENT_TAB
Line type XSDANY (not TYPE PACKING_UNIT)

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

The programmer must fill this XSDANY field correctly. For more
information see <DS:TX.SXI_PROXY_RAW_DATA>Handling raw XML data</>.

System Response

The system displays a warning for each type which is part of a
recursion. The type cannot be activated if the DDIC type to be
generatedalso contains a recursion.

How to fix this error?

To be able to activate the proxy you have to "break" the recursion by
mapping at least on chain of each recursion to XSDANY. This is done by
setting the flag <DS:DE.PRX_USE_XSDANY>Untyped mapping</> in the detail
vie of the corrosponding data type.

• What is the cause and solution for SAP error message SPRX072 - Item is part of recursion (see long text for additional information) ?

  The SAP error message SPRX072, which states "Item is part of recursion," typically occurs in the context of product structure or bill of materials (BOM) management. This error indicates that there is a recursive relationship in the item hierarchy, meaning that an item is referencing itself directly or indirectly, which can lead to infinite loops in processing.
  Cause:
  
  Recursive BOM Structure: The most common cause is that the BOM or product structure has been defined in such a way that an item references itself or is part of a circular reference with other items.
  Incorrect Configuration: This can happen due to incorrect configuration or data entry when creating or modifying BOMs or product structures.
  Data Migration Issues: If data has been migrated from another system, it may have introduced inconsistencies or recursive relationships.
  
  Solution:
  
  Review BOM Structure: Check the BOM or product structure for any items that reference themselves or create a circular reference. You can do this by examining the hierarchy of the items involved.
  Correct the Relationships: Modify the BOM or product structure to eliminate the recursion. Ensure that each item only references valid components that do not lead back to itself.
  Use SAP Tools: Utilize SAP tools such as the BOM explosion or structure display to visualize the relationships and identify where the recursion is occurring.
  Data Validation: Implement data validation checks to prevent the creation of recursive relationships in the future.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on managing BOMs and product structures.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CS03 (Display BOM), CS02 (Change BOM), or CS01 (Create BOM) to manage BOMs.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Support: If the issue persists, consider reaching out to SAP support for assistance, especially if it involves complex product structures or custom configurations.
  
  By addressing the recursive relationships in your BOM or product structure, you should be able to resolve the SPRX072 error and proceed with your operations in SAP.
