Mass Update of Premise Address

Hello Everyone,

Could you please share some ways of doing a mass update of premise addresses.

I have a requirement where I need to modify the address of more than 50k premises.  I have the premise number with me.

One idea I came across was using ISU_ADDRESS_PROVIDE to get address number and ADDR_UPDATE to update it.

I am an ABAPer and I am new to SAP ISU. So any suggestion / idea will be helpful.

Thanks,

Sam.
