English to French Tech/Engineering IT (Information Technology)

Dear colleagues,

I need this term in French language, here is some context:

Account Assignment is possible for only G/L Accounts.
If you click the box, you can calculate the formula.
Without ticking the box, you have to enter the amount manually.
Pressing the glass button, the posting screen will be displayed.
If you mark the Fiscal indicator, you can change it later.
But if you don’t specify the Fiscal indicator, you can’t post any transaction with VAT.

Thank you all!
