Corp card limit increase approval process

[jdu]

My corp card limit increase request got approved by my manager, but the transaction still failed. why?

@jdu by "transaction failed" do you mean you couldn't make the purchase? If so, this isn't anything we can help with. You should call the card issuer as they are the ones who control the card limit and purchases.

the corp card issuer is citi. They told that it is the GM who set the limit. Without the approval from GM, they will not increase the limit. I believe that is why Concur create this limit increase request work flow.  I also just notice there is alert ! icon indicated at the approval status says "Please be aware that Limit Increase Request is only completed when you receive an e-mail from GBS Travel & Expense Shared Service Center Help Desk with service confirmation". But I have not received such e-mail.
