Withholding Tax Base Amount ZERO

Dear Expert,

We are using extended withholding tax for customer side, customer withheld WHT amount and make payment to us. The setup work fine when we post manually invoices. But when we upload invoice through our invoicing system to SAP via batch input we are getting WHT base amount as ZERO. This happen when batch is process on background. If I process the same batch on display error only or foreground then WHT base amount is correctly determined.

Can anyone assist me? Thanks in advance!
