Withholding Tax is missing from Acct. Doc. at the time of creating Invoice

Dear All,

We have maintained WithHolding Tax (2C) in Customer Master.

Ideally, when we generate Invoice (with reference to a Delivery Doc.), withholding Tax data (2C) must pass-on in to the Accounting Document (for each line-item in Invoice), generated at the time of Invoicing.

But here, its missing from the Accounting Document. One should check the same and enter manually, every time.

The situation becomes worse if there are 100+ items in a single invoice.

Could any one help me in finding the reason for the same and also, how to resolve it?

Thanks in Advance,

Best Regards,
