POSTING_INTERFACE_DOCUMENT post ctax segment with negative posting (XNEGP)

Hi Vytautas,

1) it's not possible to post negative values

- sign is controlled with BSCHL (posting key) !

2) field XNEGP has another function as you might assume

here's the docu :

<i> ...

If you set this indicator, you change the way the transaction figures

for this account are updated, namely that when you make a debit posting,

the credit side of the account is reduced, when you make a credit

posting, the debit side of the account is reduced.

Use

You use this indicator if the reason for reversal you specified makes

negative postings necessary. The system then reverses all the updates of

transaction figures caused by the document you reversed.

In addition, when you enter documents, individual line items can also be

marked as negative postings, provided this is permitted for the document

type in question.

Procedure

To reverse transaction figures, set this indicator when entering line

items.
