New table PRCD_ELEMENTS in S/4 HANA

Dear SAPLearners, in this blog post we will learn about KONV SD pricing data model changes and new table PRCD_ELEMENTS in S/4 HANA. 

This blog post is part of S/4 HANA technical tutorials, you can find all tutorials here.

Introduction

We all know that SD pricing results are stored in the KONV table for sales business documents such as sales order and we have been using this table in custom code SELECT queries etc..

In S/4 HANA system, SAP has reviewed this table and new changes were implemented. When you are moving to S/4 HANA system from ECC these changes to be followed and custom code is modified accordingly.

Lets see these changes in detail

1. New table PRCD_ELEMENTS

A new database table called PRCD_ELEMENTS is introduced to replace the KONV table to store all SD document conditions. It is of type Transparent table.

The data is no longer stored in the KONV table. You need to use new table PRCD_ELEMENTS in custom code to SELECT pricing conditions.

2. CDS view V_KONV

Along with the new table and a new ABAP CDS view V_KONV is also available to get the price conditions. CDS view V_KONV can be used in custom CDS views.

Along with CDS view, an API is also available to get,update and delete the pricing conditions

3. New API 

The factory class CL_PRC_RESULT_FACTORY is used to retrieve the pricing data. The following methods are provided within the API to read, write and delete the data

GET_PRICE_ELEMENT_DB	Get price elements from DB
GET_PRICE_ELEMENT_DB_BY_KEY	Get price elements from DB by semantic key
SAVE_PRICE_ELEMENT_DB	Save price elements on DB
DELETE_PRICE_ELEMENT_DB_BY_KEY	Delete price element from DB by semantic key (one document)
DELETE_PRICE_ELEMENT_DB	Delete price elements from DB (multiple documents)
DELETE_PRICE_ELEMENTS_DB	Delete list of dedicated price elements (multiple documents)

Now you know quite a bit about data model changes to KONV. Its time to see the how we can migrate our custom code to S/4 HANA system compatible.

Here is the old code from ECC system to get SD pricing conditions.

SELECT knumv
       kposn
       stunr
       zaehk
       kappl
       kschl
       kdatu FROM konv
             INTO TABLE lt_konv
             WHERE knumv = vbak-knumv.

---

Now lets look at the new code

Using PRCD_ELEMENTS table

"new table PRCD_ELEMENTS
SELECT knumv
       kposn
       stunr
       zaehk
       kappl
       kschl
       kdatu FROM prcd_elements
             INTO TABLE lt_konv
             WHERE knumv = vbak-knumv.

Using V_KONV CDS view

" CDS view
SELECT knumv
       kposn
       stunr
       zaehk
       kappl
       kschl
       kdatu FROM v_konv
             INTO TABLE lt_konv
             WHERE knumv = vbak-knumv.

Using factory class CL_PRC_RESULT_FACTORY

TRY.
    cl_prc_result_factory=>get_instance( )->get_prc_result( )->get_price_element_db_by_key(
      EXPORTING
        iv_knumv = vbak-knumv
      IMPORTING
        et_prc_element_classic_format = hkonv ).
  CATCH cx_prc_result. "implement suitable error handling
ENDTRY.

"or other alternative way
TRY.
    cl_prc_result_factory=>get_instance( )->get_prc_result( )->get_price_element_db(
       EXPORTING
         it_selection_attribute = VALUE #( ( fieldname = 'KNUMV' value = komk-knumv ) )
       IMPORTING
         et_prc_element_classic_format = hkonv ).
  CATCH cx_prc_result. "implement suitable error handling
ENDTRY.

Haven seen the impact on custom code, now lets look at DDIC enhancements to KONV table

4. DDIC enhancements

At some times we need to enhance KONV table with custom fields catering to the customer requirements. This is usually achieved using append structure to the database table KONV

In the S/4 HANA system, you should not append directly to PRCD_ELEMENTS. Repeating this, do not append directly to the new database table PRCD_ELEMENTS 

Instead add append structure to the new structure PRCS_ELEMENTS_DATA which is included in database tables PRCD_ELEMENTS.

Subsequently to PRCD_ELEM_DRAFT which is included in database table PRCD_ELEM_DRAFT(used to temporarily store pricing results as a draft prior to save)

As we have seen in the sample code section above, CDS view V_KONV can also be used to get pricing data, therefore it is necessary to enhance the CDS view. Click here to know how you can extend a CDS view with custom fields.
