BCS General FAQs

Answers to common questions regarding General Information on how BCS integrates into SAP Oil & Gas, how it is installed and what products are supported.

I want to run the Installation Test in client 045, but the Installation Test Button is not available, how can this be?

In your client 045 (development system), you execute the QuantityWare BCS Installation Test via the Petroleum and/or Gas Measurement Cockpit (PMC / GMC).

In order to do so, two conditions have to be met:

  1. A valid BCP or BCG license needs to be installed in your system (see FAQ License Installation).
  2. The BCP or BCG BC Set has to be activated in client 045.

If these conditions are not met, the “Run Installation Test” Button (as well as the single standard test buttons) are not visible in the Test Tools Tab Strip in the PMC or GMC:

If the conditions are met,

Does QuantityWare BCP support calculations of gross and net volumes, masses and weights for crude oil?


The American Petroleum Institute (API) defines the following quantities in e.g. API MPMS Chapter 12.1.1, which can be mapped to a distinct SAP Dimension ID (DIMID):

  • GOV – gross observed volume <-> SAP DIMID GRSVOL, All UoM w/o standard temperature
  • GSV – gross standard volume <-> SAP DIMID GRSVOL, All UoM with standard temperature assigned
  • NOV – net observed volume <-> SAP DIMID VOLUME, All UoM w/o standard temperature assigned
  • NSV – net standard volume <-> SAP DIMID VOLUME, All UoM with standard temperature assigned
  • GSW –

Why do we need measurement standards-based QCI calculations within the SAP Oil & Gas system?

SAP Oil & Gas comes with an open interface – the Quantity Conversion Interface (QCI).

SAP Oil & Gas does not deliver any validated, measurement standards-based quantity conversion solution for the QCI.  Because of the complexity and risk, this has always been a customer task.

Business processes require thousands of quantity calculations per day.

For a multitude of units of measure (UoM) of various SAP dimensions – gross & net standard masses, gross & net standard weights, gross standard & observed volumes, net standard & observed volumes, energies etc. such calculations are performed.

We want to install QuantityWare BCS 3.0 into our productive system landscape and replace/extend existing legacy QCI calculations. Is this possible?

Yes. QuantityWare has spent a considerable amount of time, effort and money to ensure that a move from legacy quantity conversion calculations methods using the SAP QCI to QW BCS using the QCI and MQCI is safe and transparent. You may also install QW BCS and continue usage of your existing legacy calculations.

Read the FAQ  “How do I convert SAP legacy conversion groups from C to ABAP” for additional information.

We want to de-install QuantityWare BCS 3.0 - is this possible?

The QuantityWare BCS 3.0 package supports a de-installation.

Technically, this is achieved through selecting the Add-On component “QTYW” in the “Deinstallable components” tab-list in the SAP transaction SAINT and following the specific SAINT documentation published by SAP.

  • In a non-productive system, this procedure poses no issues.
  • In a productive system, such a process should be carefully considered and is not recommended.

    Read Note 000085 for further explanations.

What products are covered by QuantityWare BCS?

QuantityWare BCS covers crude oil and natural gas products. The Supported Products Manual provides a detailed definition on which products are supported.

The Supported Standards Manual for BCP and BCG then contains detailed support information for each single product group (e.g. LPG, Gasoline, Asphalt, LNG etc.).

Does QuantityWare BCG support Hydrogen quantity conversions?

QuantityWare BCG supports natural gas products. Natural gas products are products with a considerable methane content. Thus, Hydrogen is generally not covered. See the BCS Supported Products Manual for details – full coverage will require the availability of an international measurement standard defining an implementation procedure for Hydrogen quantity conversions.

Ideal Gas Coverage for Hydrogen – Example:

Note: If you simply require data capture and conversions of low pressure hydrogen volumes, masses and energies, you may consider utilizing a BCG ideal gas low pressure conversion group.

Does QuantityWare BCG support industrial gases like Nitrogen, Oxygen, Argon, Helium and so on?

QuantityWare BCG supports natural gas products. Natural gas products are products with a considerable methane content. Thus, industrial gases are not in scope of BCG – such gases define a second highly complex area of quantity conversions besides natural gas flow calculations . See the BCS Supported Products Manual for details.

Note: If you simply require data capture of low pressure industrial gas volumes and masses, you may consider utilizing a BCG ideal gas low pressure conversion group, where you capture the industrial gas volume and density and calculated the mass according tho the ideal gas law.

Does QuantityWare BCS cover Ethylene quantity conversions?

Ethylene is not supported with BCS 3.0. QuantityWare has analyzed API MPMS – Ethylene Density and the referenced IUPAC-88 Ethylene EOS Paper (Thermodynamic Properties of Ethylene from Freezing Line to 450 K at Pressures to 20 MPA – M. Jahangiri et al.) and could not identify an implementation guideline for software developments therein. See BCP Supported Standards Ethylene Section.

We have obtained a 4 week test license. How can we get the most out of it?

In order to get a good overview on the BCP and BCG capabilities, you should involve a certified BCS consultant as early as possible in the project.

In order to enable a quick and efficient project start, QuantityWare provides the BCP Test Manual and the BCG Test Manual.

How does QuantityWare BCS integrate into SAP PRA?

QuantityWare BCS seamlessly plugs into SAP PRA via the SAP QCI conversion groups.

However, a PRA Measurement System Expert is recommended to be available for your BCS implementation in addition to a certified BCS consultant.

The working paper QuantityWare PRA Measurement System provides detailed guidance how to proceed within such a project.

Concerning natural gas, read notes 000059 and 000063 for important details.

I want to create a TSW nomination with a gross volume UoM and receive an error. What can I do?

QuantityWare delivers new gross mass (GSM), gross volume (GSV/GOV) and gross weight (GSW) UoM (and Volume UoM for LNG – Liquid). 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:

Why do we need a new client 045 for the QuantityWare installation?

With QuantityWare BCS, a complete quantity conversion template is delivered. This template contains also more than 400 Unit of Measure (UoM) definitions. These UoM definitions are a set of SAP-defined UoM definitions – delivered also in SAP client 000 – and new QuantityWare-defined UoM definitions (e.g. gross volume, gross mass and gross weight UoM).

UoM definitions are not protected by a dedicated namespace. Thus, they may overwrite already existing UoM (with possibly different meaning) in other clients, with fatal consequences – typically requiring massive effort to resolve such a conflict. This has to be avoided by only adding the UoM to one dedicated client 045 in one system in your landscape.
