How to identify “Parent-Child” relationship process chain details in SAP BW

1.    Introduction:

In SAP BW, we could see there will be so many dependency between master date & transaction data, between different targets. Also it’s important to deliver the report on time. In order to reduce idle time, event trigger has been implemented.Sometime, we might be struggling to identify parent chain for a child chain and vice versa. So in order to get the process chain names, here I have illustrate the procedure.This document will give you step by step instruction how to identify parent-child relationships.

2.    Tables & t-code used

• RSPCCHAIN
• RSPCVARIANT
• RSPCTRIGGER

  T-Code:

• SE16 or YCAGRID

3.    Step by Step procedure to identify the relationships:

In the below given example I have used PARENT_CHAIN_TEST chains as parent and ZZNNN_TEST & CHIL_3 as child chains.

Step 1: Go to SE16 and execute RSPCCHAIN Enter the parent chain name with TYPE as ZEVENT as mentioned below.

Filter condition:

• CHAIN_ID
• OBJVERS
• TYPE

Result:

• VARIANTE

Get the VARIANTE name from it  TEST_DEMO

Step 2: Using the VARIANT name from RSPCCHAIN and put it in VARIANTE in RSPCVARIANT table Filter condition:

• VARIANTE
• OBJVERS
• TYPE

Result:

• LOW

Take LOW field value from RSPCVARIANT table.

Step 3: Go to table RSPCTRIGGER & use this LOW filed value from RSPCVARIANT table. Filter condition:

• EVENTID
• OBJVERS

Result:

• VARIANTE

Copy the VARIANTE from this.

Step 4: Go to table RSPCCHAIN once again & use VARIANTE filed value from RSPCTRIGGER table. Filter condition:

• VARIANTE
• OBJVERS

Result:

• CHAIN_ID

Parent chain name: PARENT_CHAIN_TEST

Child chain name: ZZNNN_TEST & CHIL_3

Program:

• Will show maximum 4 child process chain for a single parent chain
