SD-sap是如何确定条件值的定价值(KWERT)的?

SAP Note 1007110 : How is the KWERT determined in a subtotal?

Note内容摘抄如下：

This consulting note describes how the condition value (the XKOMV-KWERT field) of a subtotal (lines of the pricing procedure without a condition type) is determined in the pricing result.

The determination of the condition value depends on the settings in the pricing procedure used.

In all cases, it should be noted that the conditions and subtotal lines are edited successively from top to bottom in the sequence in which they are specified in the pricing procedure.

1.
 No reference steps are maintained:

The condition value of the subtotal is determined in the same way as the condition basis is determined by 'value-related' conditions.

See Note 834174, section 1.

2.
 One or more reference steps are maintained:

The condition value of the subtotal is determined in the same way as the condition basis is determined by 'value-related' conditions.

See Note 834174, section 2.

3.
 Use of a condition value formula:

You can also determine the condition value using a condition value formula. In this case, the number of the corresponding formula in the pricing procedure is entered in the 'RchFrm' column (the KOFRM field). The use of a condition value formula is more binding
than the possible maintenance of reference steps. Therefore, a condition value that is first determined according to section 1 or 2 is rejected if the formula determines a different condition value.
