For condition type K029, which of the following functions is needed for weight accumulation?

The function needed for weight accumulation in relation to condition type K029 is primarily associated with scale bases. Scale bases serve as the foundational element that allows for the calculation of condition amounts based on specific weight ranges or quantities. When dealing with weight-based pricing, it is crucial to have defined scales that correspond to different weight intervals, enabling the system to determine applicable prices according to the weight of the merchandise.

In the context of K029, which might involve scenarios where the pricing is determined by the weight of products, scale bases provide the necessary support to accumulate weight effectively and calculate the corresponding condition pricing. Each weight bracket has a precise price associated with it, thus facilitating an accurate pricing strategy that reflects the actual weights of the items.

The other functions listed have different roles in the pricing process. Structure conditions refer to the setup of various pricing elements, condition supplements typically act as additional pricing mechanisms to enhance or modify existing prices, while group conditions allow for the grouping of multiple condition types related to similar attributes but do not specifically focus on weight accumulation. Therefore, scale bases are critical for enabling the correct functionality of weight-based condition types like K029.
