what does the table IBY_TEMP_EXT_BANK_ACCTS do ?

Hello,

what does the table IBY_TEMP_EXT_BANK_ACCTS do ? what is its use.

Where are the supplier bank change requests initiated by suppliers through iSupplier portal are stored ?

On which table we need to enable the audit trail, so that we can store the information of who has initiated the change request on the supplier bank ?

Many Thanks,

Emma
