Answers to common questions regarding configuring Bulk Calculations – Petroleum (BCP) on your systems

How can I extend the density and temperature range for my product?

I have a product which has a base density beyond the supported measurement standard range, is it possible to extend the calculation range?

If the algorithm defined in the measurement standards allows so, you simply extend the range for densities and temperatures by selecting the “Extend range of standard implementation” indicator in the conversion group details screen:

Read Annex D: Standard Range Limit Extensions in the BCP Supported Standards Manual for additional information.

For our crude oil conversion group, the S&W % value increases the product mass and weight instead of decreasing it. How can this be?

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”

Our conversion group calculates the base density at 15 °C. We also need to report the base API gravity at 60 °F. Is this possible?

API MPMS Chapter 11.5 2009 provides the calculation logic for such calculations. It replaces the historical tables 3, 21 and 51 of ASTM D1250-80 Volume XI/XII.
This new logic has been implemented in an ABAP function for MQCI conversion groups, which requires a base temperature of either 15 °C or 60 °F. Template MQCI conversion group Q22A provides the configuration example:

Can we enter the density for one product in different density types (°API, relative density, absolute density)?

Yes, all BCP MQCI conversion groups can be configured in such a manner.

Example: BCP Template Conversion Group Q210:

API Gravity:

Absolute Density:

Relative Density:

In order to enable this flexible density type data entry, you simply add MQCI function module /QTYW/MQCI_CON_TDICH_VAC_DNTYP to the conversion group function module sequence in configuration:

We need to report our product density in absolute density, relative density and API gravity. Is this possible?

Our customer requires reporting of calculated base density values in three density types; all at the conversion group base temperature. How can this be achieved?

All MQCI conversion groups support such calculations. BCP configuration template conversion group Q210 can be used as a reference:

To achieve this, you simply add the function /QTYW/MQCI_CALC_BDICH_ALL to the MQCI function module sequence:

and add the six density result parameters to the reading group:

Note: If you require e.g.

We directly want to enter the base density of our products, w/o having to enter a test temperature. Is this possible?

Yes, 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 /QTYW/MQCI_BCP_PROD_DEFAULT to the Function Module Sequence (FSQ) in the configuration settings:

Then you may remove the test temperature parameter from the reading group that is assigned to the conversion group and rename the test density to base density.

We do not require the hydrometer correction. Can we remove it from our conversion group configuration?

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 reading group parameter):

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 not required – read note 000026 for all important details.

I have set my quantity value UoM L15 and KG to be rounded to zero decimals, but it is not working. What can I do?

The UoM real rounding settings are considered for all MQCI conversion groups (where rounding function /QTYW/MQCI_ROUND_ALT_QUANTITY) is assigned:

Ensure that you are not using a SAP QCI conversion group – then you will have to write your specific ABAP rounding code in SAP QCI BAdI Implementations.

My rounding settings for the density values for an MQCI conversion group are not considered for the calculation. How can I fix this?

You have copied e.g. template conversion group Q1A1 to Z1A1. For the density UoM PPG (pounds per gallon) you have maintained a rounding to 4 decimals; business requires that that rounded value is utilized for the calculation of masses.

A simple test calculation with Q1A1 shows the issue: The expected value for UoM LB is 620 540.00 LB; however, the value is calculated using the non-rounded density (while the rounded value is displayed):

This is due to the fact, that the density rounding function /QTYW/MQCI_ROUND_DENSITIES_UOM is processed after the quantity conversion model function /QTYW/MPMS_OBS_TO_ALT_QUAN:

If you position the rounding function before the quantity conversion model function:

the calculation is happening as expected:

The Q*** template conversion groups are configured to round the density values for reporting purposes,

My customer requires ASTM Table 1 UoM conversion factors. What are the configuration steps?

For MQCI conversion groups, you simply activate the ASTM Table 1 conversion factors in the conversion group detail settings:

With the QuantityWare BCS configuration templates, ASTM Table 1 conversion factors are delivered, which are accessible in your client 045 after activation of the relevant Business Configuration (BC) set. Read Note 000055 for all important additional configuration details.

My client wants to use MQCI conversion groups, where kg, lb, to, sto UoM are calculated as weights - is this possible?

Yes. The BCS configuration template provides example MQCI conversion groups that are configured such that UoM of SAP dimension ID MASS are calculated as weights (which is also the case for SAP QCI conversion groups if the air buoyancy indicator is set):

The LB value is the weight of the 10 000 gallon of product. The configuration to achieve this requires 2 (plus 1) steps:

You assign the SAP Dimension IDs for weight (and mass) DIMID.

You assign marker function /QTYW/MQCI_WEIGHT_MASS to the MQCI model function sequence.

Can I configure my products conversion groups, such that gross and net quantities are being calculated?

QuantityWare BCP contains four crude oil calculation models, that are utilized to distinguish between gross and net quantity values (e.g. gross standard or observed volume and net standard or observed volume volume).

These four models are assigned to crude oil BCP MQCI template conversion groups, e.g. Q154. For crude oil, the sediment & water fraction accounts to a difference of gross and net quantity values – see separate crude oil FAQ.

For products (e.g. gasoline, LPG, asphalt …), the gross and net quantity values are typically identical. Thus, the quantity conversion models assigned to such products are all net models and calculations for gross UoM are not supported.

We need to replace the SAP QCI legacy conversion group AROM for Benzene. How do we proceed?

SAP QCI legacy conversion group AROM (which is an example for Benzene – ASTM D1555 – 95(2000)) can be easily replaced by the ASTM D1555 MQCI conversion groups for industrial aromatic hydrocarbons:

The latest ASTM D1555-2016 version introduces a non-rounded CT(P)L for the calculations. With note 000074 , QuantityWare has shipped the required new ABAP implementation for that version. It can easily be utilized – as described in note 000074 – to update a template conversion group to that new version.
With BCS 3.0 CSP02,

How can we calculate the GSV from TCV (Total Calculated Volume) using QuantityWare BCP?

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)

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.

Example:

The free water (FW) volume is given as 120 barrels at 60 °F.

Can we calculate the Total Calculated Volume (TCV) as a target quantity for our crude oil MQCI conversion group?

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.

TCV = GSV + FW ( in appropriate UoM, e.g. FW and GSV in barrels)

You utilize a QuantityWare BCP crude oil conversion group, that is configured to calculate gross and net quantity values (see separate FAQ) . You want  the TCV quantity being calculated as additional quantity value.

Example:

The free water (FW) volume is given as 10 barrels at 60 °F.

For our ethanol DCF conversion group, we need to calculate the dehydrated ethanol volume. Is this possible?

For your MQCI DCF ethanol conversion group, you wish to enter two additional input parameters for the quantity conversions

  1. the weight % fraction of pure ethanol in your ethanol product
  2. the absolute density of pure ethanol – e.g. 0.78924 g/ml (= 789.24 kg/m³) @ 20 °C

such that the system calculates, in addition to the existing UoM in your UoM group, the liter @ 20 °C value of pure ethanol. That calculation shall be based on the following formula:

Volume @ 20 °C (pure ethanol) [L]

 = weight of product [kg] × weight fraction (pure ethanol) ÷ absolute density (pure ethanol) [kg/L]
