Quick Credit tarnsaction tax distribution

Hi Guru ' s

I have created Ap Credit Memo using Quick Credit functionality:

1) In the Invoice WorkBench, create a credit memo for the Supplier and Site
2) Enter a Negative amount
3) Navigate through the fields in the folder until you get to the Quick Credit checkbox.
Check this box.
4) In the Next field enter the Invoice Number of the invoice you want to match.
5) Save

Credit Memo Invoice lines and distributions should be created from the original invoice's lines and distributions, regardless of the actual amount on the credit memo. 

In our case invoice item and tax line has been created but tax distribution has not been created.
