Forex revaluation of principal plus capitlized interest net of w/h tax

Hi SAP Gurus,

In roll over of money market placements where interest is capitalized, capitalized interest is computed net of withholding tax. However, during foreign currency revaluation run, only the principal amount plus capitalized interest is valuated when it should be principal amount plus capitalized interest net of w/h tax. Any idea how to net off the interest with w/h tax in the forex valuation run of a contract roll over?

Thanks and regards,
