Determine Backend system based on Product category in SAP SRM

To determine product category based on backend systems following are prerequisites:

• All backend systems should be defined as unique logical systems.
• RFC destinations should be defined.
• Product Category should already been created.

      Defining a Backend System for a Product Category

  Depending on product category purchase document and follow-on documents will be created locally or in any backend system attached to them.  

The path for defining is mentioned below: SPRO →Supplier Relationship Management → SRM Server → Technical Basic Settings → Define Backend Systems → Define Backend System for Product Category.  

Determining backend system using BADI BBP_DETERMINE_LOGSYS :

We can use BADI BBP_DETERMINE_LOGSYS to define backend system based on our criteria. During determination of backend, back end system value is placed in ITEM_DATA-LOGICAL_SYSTEM field of BADI BBP_DETERMINE_LOGSYS.

” Use method DETERMINE_LOGSYS to determine backend system for Shopping carts.We can modify the value of ITEM_DATA-LOGICAL_SYSTEM based upon the value in ITEM_DATA OR ACCT_DATA.

” For Contracts:
In the standard system, the system creates contracts locally from Sourcing and SAP Bidding Engine. 

Sample code for BADI BBP_DETERMINE_LOGSYS:

Create an implementation for BADI BBP_DETERMINE_LOGSYS.

   method IF_EX_BBP_DETERMINE_LOGSYS~DETERMINE_LOGSYS.

  data :lt_item TYPE LINE OF bbpt_detlogsys_item. 

Loop at item_data into lt_item. 

If lt_item-product_type = ‘XYZ’.               “product type 

If sy-sybrc = 0.

lt_item-be_co-code = ‘3000′.                “‘company code

lt_item-logical_system = ‘ABCCLNT100′.  “logical system

modify it_item from lt_item.

Endif. 

Endif.
