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.
