The +/- Sign in SD Self-Billing 
Definition
The values for SD self-billing, item net value and item value-added tax, can be transmitted either as positive or negative values.
Use
This determines the type of processing as follows:
You must therefore make sure that these values are transferred to the corresponding IDoc field with the correct +/- sign. The GSVERF01 IDoc has no specific +/- sign field. The +/- sign is always read together with the value fields (such as E1EDP26-BETRG.)
The +/- sign for the standard VDA 4908 (as used in the
Table of Settings for Mapping in EDI Subsystem example):As a rule, VDA 4908 value fields all refer to a specific +/- sign field, that contains the appropriate +/- sign key. Therefore, a value always has to be processed along with its +/- sign information.
+ + sign (VDA +/- sign key 1)
=> the value is transferred to the IDoc segment field with no further editing
- - sign (VDA +/- sign key 2)
=> the value is transferred with preset minus sign to the appropriate IDoc segment field
Example:
Transmitted values |
Data as written in IDoc |
Net value of item: 100,20 ($) |
E1EDP26-BETRG -100.20 |
+/- sign: 2 (negative) |
E1EDP26-QUALF 003 |

Make sure that all monetary values are saved with the correct +/- sign as the monitor also displays other monetary values such as value-added tax and condition rates.
