Heraklion S’18

maam in Heraklion co. the sales staff proposes a credit limit which is authorised by the sales director, so then I don’t understand how is it a deficiency? I do get that sales staff have sales target and may propose high credit limits, which may lead to increased irrecoverable debts, but then the SALES DIRECTOR IS AUTHORISING the credit limit before it is set! so then it shouldn’t really count as a deficiency…
