Co-products in SAP IBP represent items produced simultaneously with a main product (e.g., in chemical manufacturing). They are modeled in supply planning, typically via the Production Source of Supply master data.
* Option A: The number of co-products that can be defined in the supply model is unlimitedThis is correct. SAP IBP's Production Source Item allows multiple co-products to be linked to a main product via output coefficients. There's no hardcoded limit, though practical constraints (e.g., performance) may apply, as per SAP IBP's supply planning documentation.
* Option B: The output coefficient is time-dependent and should be modeled as a time seriesThis is incorrect. The output coefficient (e.g., 1 unit of main product yields 0.5 units of co-product) is a static attribute in the Production Source Item master data, not a time-dependent key figure by default. Time- series modeling is possible but not required.
* Option C: The relationship between main product and co-product is specified in the production source of supplyThis is correct. In SAP IBP, the Production Source of Supply (e.g., Production Source Header and Item) defines the main product and co-products, including output ratios, as a core feature of supply planning, per official documentation.
* Option D: Co-production can be modeled only by supply optimizer and finite heuristicsThis is incorrect. Co-products are supported by both infinite heuristics (e.g., calculating unconstrained supply) and finite methods (optimizer, heuristics), not limited to finite planning.
Thus, A and C accurately describe co-production properties in SAP IBP, per its supply modeling capabilities.
