Please may I be advised on information update/insertion in AX 2012 for Customers, Supplier and Items.
It's the tax related information that needed to be inserted like Tax Group, Withholding tax etc.
Binda said:What impact it would have to suppliers/customers/item already have pre-existed transactions,
It depends on what field you are updating. Example - you cannot update the dimension group with different set of dimension of the item has transactions.
Binda said:Is it safe to do in the live environment?
Try running it in a TEST environment first.
