This message is an SAP HPM message. During e.g. TD or TSW process execution, material documents via SAP function module MB_CREATE_GOODS_MOVEMENT are posted, which contain quantity values which are not directly calculated by calling the QCI, but determined otherwise by TD or TSW logic (e.g. splitting quantity values into several compartments). Thus, differences may be detected when SAP calls the QCI to check if the material document to be posted can pass. If this is not the case, generic message O3 450 is issued – and not the original QCI message, which would be much more helpful.

Liquid bulk product quantity values are either determined by flow meters (dynamic measurement), tank dips (static measurement), which both result in a volume quantity value, or via weighing bridges, which determine the weight (but not directly the mass*) of the product:

Since a weighing bridge is surrounded by air, the product (and also e.g. the carrying truck) floats in the air – there is a small but measurable air buoyancy effect to be considered, such that the measured weight value is not equal to the mass value of the product, which one wishes to determine.

Thus,

The ASTM D1250-80 /API MPMS Chapter 11 – 1980 implementation guide specifies, that absolute density values must be rounded to the nearest 0.5 kg/m³ value.

Example:

An input value of 781.3 kg/m³ is internally rounded to 781.5 kg/m³ before it is utilized for the computation of the base density or the VCF and subsequently for the mass values; a value of 781.1 kg/m³ is rounded to 781.0 kg/m³.
This rounding specification leads to the peculiar effect, that a base density value of e.g. 780.3 kg/m³ at 15 °C is rounded to 780.5 kg/m³ (at 15 °C) and a value of 780.1 kg/m³ at 15 °C is rounded to 780.0 kg/m³ (at 15 °C):

The air buoyancy indicator concept is an SAP QCI legacy concept, based on DIN 51757, to support calculation of weights.

You define the air buoyancy “factor” in the material master, typically 1.1 ( kg/m³), as defined in DIN 51757. Then, if you set the indicator during business transaction processing, the SAP DIMID MASS UoM are calculated as weights ( the base density in air in kg/m³ is internally calculated by subtracting the 1.1 kg/m³ value defined in the material master from the base density in vacuo) .

For pressure value data it is important to differentiate between absolute pressure values and gauge pressure values.

For all conversion groups, that are configured to require entry of pressure values, these values can either be a gauge or an absolute pressure value.

The behavior described in this FAQ question is defined within dedicated MQCI pressure conversion functions, that convert gauge pressure values to absolute pressure values – visible to the user and using the base pressure UoM as absolute (or vice versa).
If you do not require this behavior, you may replace the MQCI pressure conversion function with the corresponding function that treats all UoM as either all absolute or all gauge values,

Answer Continues... View Full Answer Page

Yes.
This is in principle possible.

However, one important fact to consider is that vapor pressure values are required as absolute values for the vapor space calculation, whereas observed/flowing pressure values may be required as gauge values for the CPL calculation.

Therefore, no standard MQCI pressure correction function may be assigned to such a conversion group (which all assume that both values are either both gauge values or both absolute values).

Thus, a detailed specification of this requirement must be available to a certified BCP or BCG consultant, who then performs a feasibility analysis with QuantityWare experts.

The definition of the Total Calculated Volume (TCV) is:

TCV equals gross standard volume (GSV) plus free water (FW) – API MPMS Chapter 12.1.1.

Thus, GSV = TCV – FW ( in appropriate UoM, e.g. FW and GSV in barrels, all at e.g. 60 °F standard temperature)

You utilize a QuantityWare BCP crude oil conversion group, that is configured to calculate gross and net quantity values (see separate FAQ) . You want to enter a TCV value as transaction quantity and the FW value for the calculations.

Yes.
In principle, this is possible. A UoM is defined with an internal key (T006-MSEHI), a technical key and a commercial key. The commercial key (as the internal and the technical key) has to be unique in your clients, but can differ from the technical or internal key.

Example:

Business users require UoM LTA (Long ton, in air) and TOA (ton, in air) to be displayed as LNT and MT.

For each UoM, you define the number of decimal places (for display). Data input and display of result parameters via the SAP UI (e.g. QCI sub screen) is restricted to that number of decimals.

Note: For real rounding of calculation results, you define additional real rounding settings.

LPG quantity conversions support two vapor space scenarios. For each scenario, one indicator is relevant.

Scenario A: You perform an opening and a closing dip measurement (e.g. for a loading process shore-to-ship) to determine the transferred mass of LPG (e.g. by using SAP Tank Management and implementing your delta calculation logic in a SAP Tank Management BAdI):

Summary: In this scenario, you perform two calculations (opening and closing dip calculation) with the “Apply vapor corr. (tank dip)” indicator set. The transferred mass is calculated by subtraction.

Example:

Enter a transaction quantity of 10 000 m³ (SAP UoM M3):

Apparently, the gross ton value (UoM GT) is lager than expected, also the net ton (UoM TO) and the gross and net weights (UoM GTA and TOA) for a S&W fraction of 0.1 %. How can this be?

Answer: For S&W calculations, it is important to select the correct UoM for gross observed or gross standard volumes (GOV, GSV), which are typically the transaction quantities. By design, M3 is a NOV (Net Observed Volume) UoM. Thus, the calculation is performed “backwards”

All BCP MQCI conversion groups can be configured in such a manner.

Example: BCP Template Conversion Group Q2A1:

Here you only enter the observed product temperature and the base density  as input parameters. Then, the VCF and all densities in air values are calculated, as well as all quantity values.

Technically, this is achieved by adding MQCI Function Module

The hydrometer correction may only be required, if you enter an observed density that is determined with a glass hydrometer. If you utilize an ASTM D1250-04 implementation, you may simply remove the hydrometer function (and also remove the hydrometer indicator from the reading group):

ASTM D1250-80 implementations contain a built-in (by measurement standard definition) hydrometer correction logic, which requires that you actively turn the correction off if it is not required – read note 000026 for all important details.

QuantityWare BCS implementations for LPG/NGL, LNG and natural gas support both the data entry of absolute or gauge pressure values. Crude oil and products CPL calculations do require entry of gauge pressure values.

The conversion group configuration for LPG/NGL, LNG , natural gas, crude oil and products can thus be made to support data entry of either gauge or absolute pressure values – by adding or removing dedicated MQCI pressure calculation functions to the conversion group function module sequence.

For the quantities gross mass (GSM), gross volume (GSV/GOV), net weight (NSW), gross weight (GSW) and Volume LNG – Liquid, QuantityWare delivers new UoM . These are linked to new SAP dimension IDs – DIMIDs. Quantity values with UoM belonging to such new dimensions are valid Nomination scheduling quantity values. However, TSW Nomination carries out a standard UoM validation check which allows SAP DIMID MASS or VOLUME only.

You can disable this check (or write a custom code check): To disable the check, go to the SAP IMG and change the UoM Check Message Type:

Vapor space calculations are defined in measurement standard ISO 6578. The calculation simply adds the vapor mass (and vapor energy or weight) to the appropriate liquid mass, energy and weight quantity (in any given UoM).
Volume quantity values are not updated with the liquid volume quantity value equivalent to the vapor mass and thus do contain the liquid product quantity value only (in any given volume UoM).
Therefore, it is important that the base UoM in the SAP material master is either a mass, weight or energy UoM.

QuantityWare BCS delivers a configuration template that contains two different types of conversion groups – SAP QCI conversion groups and MQCI conversion groups.

Both types utilize the proven SAP QCI interface to oil, gas, and energy business processes and thus integrate seamlessly into all processes.

• SAP QCI conversion groups are limited in their functional extend and are typically used in legacy environments.
• MQCI conversion groups offer full functional calculation flexibility – supporting all available measurement standards and thus should be used in greenfield projects.

1. In SAP ECC systems, you cannot change the UoM group or add or delete UoM to an existing UoM group, once stock has been posted for such a material.
2. In SAP S/4HANA systems, a UoM group that is assigned to a material can be extended with a new UoM, also in production. However, this requires usage of a dedicated extension report tool provided by SAP – Read SAP Note 2328459 for details. Thus, such a UoM group extension (adding a new UoM to an existing UoM group) should always be performed by an experienced HPM consultant.

Yes.
Changing the conversion group in the material master is supported by SAP since ERP Release 4.6B.  You simply have to observe the general rule, that an HPM material (for which stock levels are posted in parallel in several  UoM – which are defined in the UoM group) cannot be changed to be a standard material and vice versa. This means, that you cannot remove a conversion group completely (i.e. leaving the entry field blank), once assigned and material documents have been posted.
