Service tax code not properly updated in BSEG

Dear experts,

We have an issue of service tax.We have defined service tax code as S9 and most possibly it is not configured in a right manner or what.Present issue is that unlike other ( MWSKZ ) ie tax codes in BSEG, we do not see business area getting populated in BSEG table for service tax.In addition,PO as well as line items are not getting populated in BSEG table for service tax.Only we see tax amount and it is actually difficult to relate with PO and line item as it is not coming in table.

Secondly, normally tax is automatically computed but in our practice user manually enter the service tax.

Now i want to retrieve these figures in one of our landed cost

report but as the link ebeln ebelp is not present,this assignment has become actually tedious.

Can someone impart his precious direction ?
