1 OVERVIEW

1.1 Introduction

This document is about the new Stateless Pricing Remote API of the IPC Pricing Engine that is available from

Support Package 29 of the Software component SAP_AP.

The high level use case is to deliver price information about one or several items to a non-SAP caller using SAP

master data and customizing settings. For example this can be used within the context of a Third party web shop

catalog. The caller requesting the price(s) needs to provide the pricing context to the pricing engine, i.e. no

customizing determination is done. As the name of the API reflects, the pricing engine will not retain the state of

the pricing document once remote call has been processed. Hence, this API for performance reasons may not be

suitable for highly interactive scenarios such as a shopping basket.

The API can be easily invoked using RFC protocol (for example using SAP Java Connector from Java

environment).

1.2 Prerequisites

SAP_AP 7.0 in the system must be based on support package level 29 or above.

1.3 Functional limitations

Tax determination via the TTE (Tax Transaction Engine) is currently not supported

Pricing results are not persisted at engine side

Loading of existing pricing document and its modification is not supported

1.4 Further Information

There are several additional information available elaborating different topics more detailed.

1.5 SAP Support for Stateless Pricing API Usage

Support issues with the Stateless Pricing API are not covered by a normal SAP support contract. This document

only helps to implement and should not be regarded as part of the standard delivery. In case of troubles SAP

support may request you to use the (remote) consulting service.

2 DEVELOPMENT

2.1 Description of the API

With Support Package SP29 of SAP_AP onwards, the new Remote Function Call (RFC)

SPE_CALCULATE_PRICE is available. This is Java Function Module that can be called via SAP Java

Connector (SAP JCo). It allows executing pricing (price determination and price calculation) with only one call.

Below you can see the signature of the Java module. The documentation of the ABAP structures and fields are

available in your backend system where the RFC SPE_CALCULATE_PRICE is located.

In the next chapter you can see an example how to call it for better understanding.

IT_ITEM_ADDNL_INPUT

IT_ITEM_ADDNL_INPUT is used for supplying item level additional attributes those are rarely (depending on

use cases) needed for price calculation. While filling entries into this parameter table you need to make sure

that it’s indexing should be matching with an entry in IT_ITEM_MAIN_INPUT. For example your first entry

in IT_ITEM_ADDNL_INPUT should correspond to first entry in IT_ITEM_MAIN_DATA. This is because

internally indexing is used while fetching entries from this table since index based read is faster.



DAYS_PER_MONTH No Needed only if you want to influence time based period factor

calculation. Indicates the number of days a month should be

accounted with.

DAYS_PER_YEAR No Needed only if you want to influence time based period factor

calculation Indicates the number of days a year should be

accounted with.

HOLIDAYS No Needed only if you want to influence time based period factor

calculation. Can be filled with individual days to reduce the

calculated values

VARIANT_CONDITIONS No For calculating conditions based on variant keys and factors

IT_ITEM_ATTRIB_INPUT

IT_ITEM_ATTRIB_INPUT is used for supplying pricing dynamic attribute set which is required for condition

finding and user exit executions. It is based on pricing procedure customization. You can retrieve this

customization information using RFC SPC_GET_PRICING_PROCEDURE_INFO. While filling entries into

this parameter table you need to make sure that it’s indexing should be matching with an entry in

IT_ITEM_MAIN_INPUT. For example your first entry in IT_ITEM_ATTRIB_INPUT should correspond to

first entry in IT_ITEM_MAIN_DATA. This is because internally indexing is used while fetching entries from

this table. Because index based read is faster.



FIELDNAME Yes Attribute name

FIELDVALUE Yes Attribute value


12

IT_ITEM_TIMESTMP_INPUT

IT_ITEM_TIMESTMP_INPUT is used for supplying timestamps which is required for condition finding. It is

based on pricing procedure customization. You can retrieve this customization information using RFC

SPC_GET_PRICING_PROCEDURE_INFO. While filling entries into this parameter table you need to make

sure that it’s indexing should be matching with an entry in IT_ITEM_MAIN_INPUT. For example your first

entry in IT_ITEM_TIMESTMP_INPUT should correspond to first entry in IT_ITEM_MAIN_DATA. This is

because internally indexing is used while fetching entries from this table. Because index based read is faster.



FIELDNAME Yes Timestamp name

TIMESTAMP Yes Timestamp value

IT_MANUAL_COND_INPUT

IT_MANUAL_COND_INPUT is used for supplying manual conditions.


ITEM_ID Yes Item identifier. For adding condition at header level set it with

initial GUID

COND_TYPE Yes Condition type

COND_RATE Yes Condition rate

COND_CURRENCY Yes Condition currency

COND_UNIT_VALUE No Condition pricing unit value. Mandatory for non –percentage

and non-fixed amount condition

COND_UNIT No Condition unit. Mandatory for non –percentage and non-fixed

amount condition

CALC_TYPE No Calculation type. If calculation type need to be changed while

adding the manual condition. It will be allowed if and only if

condition type customization is setting is done in that way

2.2 Example how to call Stateless Pricing API

Here is an example which shows how you can invoke stateless pricing remote API using SAP JCo (Java

Connector) client from Java environment

Example call of Pricing Stateless Pricing API

public class ExampleStatelessPricingAPI { public static void main(String[] args) { System.out.println("--- START ---"); // connect to SAP system JCO.Client client = null; try { client = JCO.createClient( "100", // SAP client "myUser", // User ID
