Hi Nadim,
I want to explain to you some pattern for tax.
Scenario, you have a payable amount 1100 with tax rate A (10%)
Pattern 1: Tick on Calculate tax checkbox
You enter
PK 31 - Vendor: 1100 (tick on Calculate box)
PK 40 - Expense: * (tax code A)
When you simulate, you cannot see the tax line item. But after posted, the document will be:
PK 31 - Vendor: 1100
PK 40 - Expense: 1000
PK 40 - Tax: 100
Pattern 2: Enter manual tax amount
You enter
PK 31 - Vendor: 1100
PK 40 - Expense: 1000 (tax code A)
And click on Taxes button, enter the tax amount 100.
When you simulate, you will see One line item 50 in the end. After posted, the document will be same:
PK 31 - Vendor: 1100
PK 40 - Expense: 1000
PK 40 - Tax: 100
Pattern 3: Enter manual tax line item
You enter
PK 31 - Vendor: 1100
PK 40 - Expense: 1000 (tax code A)
PK 40 - Tax: 100.
When you simulate, you will see 3 line items. After posted, the document will be same:
PK 31 - Vendor: 1100
PK 40 - Expense: 1000
PK 40 - Tax: 100
In you case, you can use pattern 1 or pattern 2, they will be OK.
Hope it's helpful.
Regard,
Julie
