System generated Tax line items are not carrying Text in the transaction?

Hi,,

Here my question is when we create any transaction in FB60 or FB70 by using tax indicator.

Tax is calculating properly and getting proper line items in the simulation screen.

But tax generated line items are not having text and I have to enter their.

If I go back and simulate the document tax line items text will be disappeared and again I have to enter text.

Is there any way to pull text from the expenses account to tax line items(system generate line items) which I mention in the line item text before simulation.

Please advise.

Thanks,

Raj
