Answers to common questions regarding general Information on how BCS integrates into SAP Oil, Gas, and Energy – how it is installed and what products are supported.
Client 045 is considered by QuantityWare to be the “single source of truth”, exclusively containing QuantityWare BCS customizing and configuration.
It acts as proof of successful technical and functional installation of BCP and BCG, which is required for QuantityWare support.
It is used e.g. if new products require support and thus new template conversion groups need to be selected from the template and subsequent implementation, new UoM are required, or measurement standard changes require new template conversion group selection and configuration.
Thus, do not delete it.

Solid products (“solids”), that result from petroleum refining, are supported – if they need to be treated as SAP HPM (Hydrocarbon Products Management) material in your ERP system. Solid products are those, where no temperature or pressure dependance of relevant quantities (volumes and densities) is observable.
Solids (e.g. sulfur, pet coke, and others …), do not fall into the general product support (liquid or gaseous products*) as defined in the BCS Supported Products Manual . For solids, several solutions are available, which need to be exactly specified (conversion model,

Ethanol is globally utilized as an important feedstock and in gasoline blends (e.g. E5, E7 , E10 blends).
Pure ethanol – 95% ethanol and higher:
- Ethanol conversions are supported with Brazilian standard ABNT NBR 5992-80, ABNT NBR 5992-08 and ABNT NBR 5992-16. This standard is implemented for all versions in BCP 3.0. This standard calculates volumes (at the base temperature of 20 °C and various alternate temperature bases) and masses and weights (total product and alcohol portion) based on the input values (mass ratio and observed volume or test density) for a temperature range of 10 °C to 40 °C.

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 SAP QCI/MQCI conversion group configuration – based on well defined measurement standards implementations defined in your BCS implementation project.

As described in the blog article “Complete compromise of an SAP system” (SecurityBridge Group 2024), if one member of the “Operating System – Database – SAP System” trio falls, they all fall.
Gaining access to “rsbdcos0” is named as a method by which operating system calls could be executed by a SAP user, but why bother when “CALL SYSTEM” is being used?
“CALL SYSTEM” can be used in a legacy SAP Oil, Gas, and Energy (SAP OG&E) system environment to execute external files (generally referred to as “API-C” calculations) creating risk of an uncontrolled “bridge” within an ERP-level SAP OG&E system to trigger operating system (OS) –

For SAP legacy template conversion groups for crude oil and products, an automated conversion tool from C to ABAP is available within the PMC.
This is not the case for asphalt legacy conversion groups:
Historically, SAP delivered exactly three asphalt conversion group examples, SAP template conversion groups ASPA (API gravity, 60 °F base temperature), ASPR (relative density, 60 °F base temperature) and ASPD (absolute density, 15 °C base temperature). Customers could activate any of these at their own risk. Technically, an example ABAP function module – based on superseded measurement standard ASTM D4311-1996 –

QuantityWare BCG supports the ISO 6578 (Version 1991 and 2017) density calculations for LNG. As described in Note 000076, the main difference between these two versions is the definition of configuration data, i.e. the k1 and k2 factors and orthobaric molar volumes. Customers may wish to utilize their own, contractually defined, calculation data sets.

ISO 6578 provides two density calculation methods for LPG density calculations, based on the known chemical composition of the LPG. Very large factors may have to be applied for the correction of observed density to density at standard temperature, e.g. a correction for the effect of a temperature difference of 60 °C may be necessary for refrigerated propane. Provided that the LPG does not contain more than 20 % of unsaturated hydrocarbons, the correction tables introduced in ISO 91 shall be used for volume corrections. Thus, ISO 6578 is intended for LPG products that contain more than 20 % of unsaturated hydrocarbons (e.g.

You are upgrading an SAP OG&E S/4 system (e.g. 1809 to 1909) in which BCS has been installed and used.
All QuantityWare (QW) BCS-supported SAP OG&E releases are listed in QW Note 000086 along with the corresponding QW BCS version. Retain QW BCS in your system during the upgrade procedure between S/4 releases by selecting “KEEP VERSION” in the phase PREP_EXTENSIONS/IS_SELECT. Ensure that all valid maintenance transports and files have been imported to the system before starting the upgrade preparation.
