Withholding Tax Amount display in FBL1N

Hi,

In FBL1N line item display for Vendor,we are not getting the withholding tax amount in the line item display when we post any document in MIRO(document type RE),but WHT amount is displayed when we post through FB60(doc type KR).

Why this difference is coming???

How to rectify the problem??

Please Suggest.

Thanks & Regards

Sujay
