Migrate BP data from legacy system to SAP S/4HANA using the API CL_MD_BP_MAINTAIN

Hello experts!!

Could someone help me, please?
I was searching about the new SAP tool, Migration Cockpit (LTMC), to migrate BP data from a legacy system to a SAP S/4HANA, and I found this SAP note:

It says that the RFC used until now is obsolete and recommend to use the API CL_MD_BP_MAINTAIN. However, it doens't give any details about how to use it.

Do you have any directions to give me about how to proceed?

Thank you so much!

    Hi Amanda,

    Unmesh Salvi is right as it requires knowledge about creation of custom object in S/4 Migration Cockpit.

    I cannot talk from BP perspective as i am not expert in that area, but i can give you an idea on how to use the infromation from note to implement a Migration cockpit object.

    Below are the high level steps to be followed:

    1. Create a function module which accepts structure CVIS_EI_EXTERN , has a flag to simulate test mode and BAPIRET2 structure returning messages.

    2. In the function module you can call VALIDATE_SINGLE method and then MAINTAIN method of the class CL_MD_BP_MAINTAIN with the data as per note 2417298.

    2. Create a custom object in LTMOM using the function module created as mentioned above. The source structure definition can be deduced from CVIS_EI_EXTERN

    3. Generate object, download excel and enjoy!!

    Please note that there can be multiple designs in implementation, like for example, you can still breakup the CVIS_EI_EXTERN structure for file template and then prepare it in the function module.

    Thanks and Regards,

    Just call method in Function Module and pass the data to the same.

    or join course on for LTMC and Data Migration to SAP S/4HANA

    Hi Amanda,

    where you able to create a custom migration object using the API mentioned? I am currently trying the same, but using the fm BAPI_BUPA_CREATE_FROM_DATA. No errors occur during upload, but neither is any data uploaded. So it would be good to hear if your approach was successful.

    Thanks and regards,
