Customer clearing with TDS f.13

Hi,

I have two customer Documents with 1000- and 1000+. In customer master data i have given withholding tax type,code, dates.

While clearing in f.13, i am getting following error-"Items with withholding tax code for customer subject to withholding tax"

But if i delete tax details in master data and run f.13 , documents are getting cleared without any error.

Is it standard ? can i suggest client to do the same for clearing ?
