can we load customer using FBDI using multiple user at a time for 3 lac plus customer records

Hi Expert,

can we load 3 lac plus customer master & reference account using simplified FBDI using multiple user at a time, if can load what is the precaution to be take care while loading the data, is there any tools available from Oracle which can be used to manage bulk data & can also manage the error smoothly.

One user can create batch of 10 to 15k of customer and can load in multiple batch but they have to manage error for all batch will be difficult.

let me add some more detail on this ask.

Can we do parallel uploads of customer master using simplified FBDI, and How many parallel upload can run at the same time without causing any stress on the application.
