Industries Order Management supports many-to-one decomposition in which several source products contribute to a shared technical product. When two source products supply an attribute with the same name, decomposition does not fail. The shared technical product receives one resulting value, with the value from the most recently edited or added source attribute taking precedence for the generated fulfillment data. The recommended configuration follows the native Communications Cloud responsibility boundary: catalog and CPQ determine the commercial request, while Order Management, OmniStudio, or the relevant platform service performs the downstream processing required by the use case. The duplicate attribute name is therefore not a design-time or runtime error and it does not automatically become null. If conflicting values are possible, the catalog should establish deliberate ownership or normalization so that the precedence rule does not create an unintended result. Avoiding duplicate logic is important because repeated rules across catalog, integration, and orchestration layers quickly become inconsistent as products evolve. The selected approach keeps the authoritative data in the correct object model, supports later lifecycle operations, and minimizes additional processing or manual intervention. It should be implemented declaratively wherever the platform feature can express the requirement, with customization reserved only for behavior that genuinely falls outside the supported framework.
