High volume BP Data Loads 1M+ to MDG and DRF to S/4 HANA 1909

Need some information on Business Partner Data Migration to MDG for very large volumes and the best practices around it.

We have a customer with 1M+ Business partners in legacy systems and we need to decide on the best approach to load data to MDG(Hub based) and S/4 HANA 1909.

  1. If we load 1M + BP to MDG first and use DRF to replicate to S/4, how is the DRF performance for such large volumes into S/4. Customer wants to know how long has it taken for other customers, so it can help us extrapolate and predict load times for 1M records.
  2. Is loading into MDG and S/4 separately and then reconciling the Keys and GUID via Key/value Mappings a better/preferred option, than DRF to S/4, for such high volume scenarios?

Any inputs will be very helpful on the above 2 questions.

    Hi Gopi,

    Here's my answer based on my experience. We loaded ~50K customer records into MDG hub (1809) and then replicated to ECC with DRFOUT. Please note that CVI was set up to generate the BP in the background.

    1. 50K customer records (DEBMAS, ADRMAS, ADR3MAS) took about 3 hours to load into MDG - Data Services was used for the load. DRFOUT was pretty slow. Took about 8 hours to complete the replication. In your case you would be replicating the data into S/4 - this may be faster.

    2. I would say YES. Load the data twice a. Initial data load into MDG (create) b. Load the same data into S/4 again (Create/Update based on the scenario)

    Happy to answer if you have more question. Keep this thread posted on how the load goes.

    Regards,

    Magesh
