WHT to pay for issued bonds - Product Type 04X

Dear All,

How can we customize the WHT to pay for issued bonds - product type 04X?

My steps :

A) activated taxes for 04X

B) assigned taxes to update type SAM7001 for interests to pay. I assigned update type SE3006.

My posting with FWZE/FWSO looks like follows :

SAM7001 Debit Interest to pay 1500 u20AC

SAM7001 Credit technical 1500 u20AC

SE3006 Debit WHT to pay 375 u20AC

SE 3006 credit technical account 375 u20AC

==> Problem: It looks like that we are paying now 1500 u20AC + 375 u20AC = 1875 u20AC so we are paying the WHT twice....

Questions:

A) What am I doing wrong?

B) Did I select the wrong update type.

C) any help? How can I resolve this?

kr,

Stef
