Withholding tax code and Withholding tax type relation

Hi All,

Here is my requirement:

I need to get the WT code description for the tax codes I get in BSIS (BSIS-QSSKZ). The problem is when I try to get the same from T059ZT, I need to have the two key fields WITHT (Indicator for withholding tax type) & WT_WITHCD (Withholding tax code).

But from BSIS I am having only the field QSSKZ (Withholding Tax Code)and not the WT type.

I need to know, how can I get the WT type based on WT code? I tried WITH_ITEM but its of no use, as it has both these fields as key fields.

Thanks in advcane.
