I am sure many of us have come across a number of use cases where we need to perform real-time reconciliation of S/4HANA data in BW/4HANA system. Let us consider one of the most critical use cases and go through how this can be achieved.
In many companies, BW system is being used for financial month-end closing requirements. As part of it, the financial related data is extracted (e.g.: 0FI_ACDOCA_10 – Universal Journal Entry) from S/4HANA system and it is fed into a standard/custom ADSO in BW system.
During the month-end closing (specifically last 2 to 3 days), the financial data is frequently updated in S/4HANA system and the same data is extracted and reported (e.g.: Profit & Lost Statement, Balance Sheet, etc.) in BW system. It’s an iterative process.
We need to make sure that the data in BW system is in synch with S/4 system. The challenge for real-time reconciliation is that the data is extracted in batch mode (e.g. Every 15 mins) or in streaming mode in BW/4HANA and the data is continuously updated in S/4HANA. So, we need to have a timestamp in source and target system and tools to read the data in real time.
Refer to the architecture diagram below to achieve the real-time data reconciliation.
