How does the QCI tolerance check for manual/external quantity value entry work?
SAP QCI conversion groups, as well as the MQCI conversion groups, support direct entry of quantity values from external systems, e.g. TAS systems.
The external values may have been calculated / determined in an unknown way, but are believed to be trustworthy and thus required in the SAP system as is. Once entered into the SAP system, they are compared with the SAP QCI / MQCI calculated results, which are defined by the conversion group configuration – based on well defined measurement standards implementations in your implementation project.
If deviations occur, the system checks that these deviations are within the limits defined in the conversion group. A conversion group is assigned to one or more materials in the SAP material master:
The QuantityWare template conversion group tolerances are set to 0.1% deviation, which triggers a warning message, if quantity value differences between external and internally calculated values are below or above that limit and 0.5 % deviation, which triggers an error message, if quantity value differences between external and internally calculated values are below or above that limit.
Technically, these limits can be increased largely. QuantityWare MQCI conversion groups can also be configured to work with a tolerance group – see BCP Documentation Reference Manual – Chapter 6.11. for details.
Externally entered/passed values, that deviate from the validated SAP QCI / QMCI calculated values, are marked with an indicator (MANEN) in business documents.
Changes in the tolerance settings and final adjustments should be made by a certified QuantityWare consultant. These settings are critical for a working gatekeeper functionality within your SAP system. If you have assigned a conversion group to a material, where deviations between the externally calculated quantity values and the SAP calculated quantity values (SAP QCI or MQCI) are rather large, the fundamental questions are:
- Why do the external values differ from the well defined, measurement-standards based internal SAP QCI calculation results?
- If we assume that the external calculations are also based on a validated – measurement standards based – calculation logic, why is that logic not mapped within a validated QCI conversion group?
- Why is a conversion group assigned to the SAP material master which differs so much from the external calculation results?
If large deviations need to be accepted for a few materials, this may require either an increase of the tolerance levels in the existing conversion group (affecting all materials assigned to that conversion group!) or a dedicated, newly configured conversion group for such materials, where – for whatever reason – a close match between the external and internal values cannot be achieved. Involvement of a certified QuantityWare consultant is crucial.
The following messages are raised if tolerance levels are exceeded:
SAP QCI conversion groups:
O3 021 Manually-entered quantity in & is within the high-warning range
O3 022 Manually-entered quantity in & is outside the error range tolerance (low)
O3 023 Manually-entered quantity in & is outside the error range tolerance(high)
O3 024 Manually-entered quantity in & is within the low warning range
MQCI conversion groups:
/QTYW/QCI 004 External quantity in & is outside the error range (low)
/QTYW/QCI 005 External quantity in & is outside the error range (high)
/QTYW/QCI 006 External quantity in & is within the high warning range
/QTYW/QCI 007 External quantity in & is within the low warning range
