F-28 / Tax Code Input

Question

Hi all,
I am facing a problem while doing F-28.
I am trying to post the incoming payments for a customer and trying to clear the open items.
Now, when i select the open items and then simulate the document, I get an additional automatically generated line item ( a new GL account ) with the description " Realized exchange rate gain on sales ".
I need to correct this line item by entering a tax code here. Actually this is the business requirement ,  to input tax code under the gain/loss GL account upon posting of receivable clearing in customer account.
So i have to give the Tax code for this line item. So when i go into the line item and reach the " correct G/L account line item " screen, i see that the tax code is greyed out ! I cannot input any tax code here.
My question is that : Why is the system creating an additional line item and posting a new line item with the G/L for Realized exchange rate.
Where is this linked to the customer invoice ??
Second is : How can i make this Tax code field as ready for input once i simulate and try to correct the line item.
If this is not possible to input the Tax code field for this line item , in F-28 , then is there any alternative where we can input the tax code for this automatically generated line item ?
I also checked the customer invoices where were being cleared in F-28 , and in both the documents, the tax code is given in all the line items.
Why does this line item does not have the same Tax code and why is this greyed out .....
Please help me input the tax code here..
Many thanks in advance..
Srikanth.

Answer 1

Hi Dear,
Ans for 1st one: In your customize settings it is configured that if any exchange rate difference( gain/loss) is there that should be posted to that particular account
thats why system is picking the g/l account and posting to it.
To answer your 2nd querry i need some more clarification
you said that its a incoming payment then no need of tax codes, if as per your co specific requirement it has to give then you are specifying non deductable tax code (A0) only r you are assigning any other.........
Automatic generated line items are triggered after simulating,
Once you simulate the document system will not allow any changes
to meet your requirement one work around is there ..........
if you are ok with A0 tax code you can default it in G/L master it self.
