Hi friend,
Alternative Calculation Type, Requirement, Cond Base values are used in Pricing to meet the not so common business requirement. The normal prcing requirements can be mapped without using them .
Coming to the AltCalType, we have to use routines which stores the business logic and can be used against the relevant condition type as per the business requirment. The routines , in other words are the formulas that are defined in Tcode- VOFM by the abapers based on the logic given by the functional consultants.
Remember: The routine is applied against a condition type in the pricing procedure
Some of the standard Altcaltype routines are as below
<b>Routine /Formula :- 15</b>
A company has defined minimum prices for materials.
When a material is sold, it should not be sold for a price below the predefined minimum price. When pricing is done for a sales document line item, if the net price of the item falls below the minimum, the system should automatically compute a surcharge to bring the price up to the minimum price. To accomplish this, the user would define the minimum prices using the condition type PMIN. PMIN would be defined in the pricing procedure and condition value formula '15' would be assigned. Using the formula, the system compares the minimum price with the net price calculated to that point in the pricing procedure. If the minimum price is not met, the system computes the necessary surcharge and assigns it to the PMIN condition line.
<b>Routine /Formula :- 48</b>
Formula '48' was delivered to ensure that the down payment amount the user offsets in a billing document does not exceed the actual down payment value. Condition value formula '48' is assigned to the condition type in the pricing procedure representing down payments (R/3 delivered condition type AZWR).
Let me know for any further clarifications.
