How To Fix NAA677 - Do not use exclusive indicators for access sequences relevant to rebates

NAA677 - Overview

• Message type: E = Error

• Message class: NAA - Subsequent settlement (Purchasing)

• Message number: 677

• Message text: Do not use exclusive indicators for access sequences relevant to rebates

What causes this issue?

Subsequent Settlement contains functionality for the subsequent updating
of business volumes. For reasons of performance, these functions do not
use price determination, they only simulate price determination.
In this process, conditions (calculation schema, access sequence) are
checked as long as internal fields of price determination are not used.
However, it is not possible to take account of exclusive indicators, or
condition exclusion groups and exclusion indicators.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

It is very difficult to get an overview of the individual
constellations. SAP therefore urgently recommends that (for access
sequences relevant to volume-based rebate) you do not use exclusive
indicators or condition exclusion groups or exclusion indicators.
Otherwise, the system may carry out unwanted updates.
The "subsequent business volume update" function does not permit the
functions "exclusive indicator", "condition exclusion group" and
"exclusion indicator" (that is, you must use either the subseqeuent
business volume update or the exclusive indicator/condition exclusion
group/exclusion indicator)
SAP urgently recommends that you do not use the "subsequent business
volume update" function.
Tip:
A condition of type K001 with 5% for all materials from supplier
"Supplier1", but only 3% for materials "Mat1" and "Mat2", can be mapped
as follows: Materials "Mat1" and "Mat2" are assigned to settlement group
"A1". Two condition records are entered:
K001 Supplier1 5%
K001 Supplier1/A1 -2%
This solution means you avoid using exclusive indicators but requires
two condition records.
