Product Modeling Gap

● Post-merger consolidation:harmonize SAP and non-SAP systemsfor sales and configuration

● SAP ERP/PLM (VC) + SAP CRM 2007 (IPC)● Migration challenge:

How to migrate 6 product lines / more than 240 different products to VC / IPC?

(CWG 2009 Berlin talk by Gerhard Hering, NSN)

Company-wide generic product structure

Standardizedproduct descriptions

Standardized Product Descriptions

● Product structure● Characteristics

(domains, texts, default values, interface design)

● Quantity rules for materials

● Other rules

In-house product experts specify product models

Problems

Excel „template“ used as graph paper● pseudo code – manual translation required● manual tracking of changes● no guarantee for completeness● no specific tool support – just general Excel● first visual feedback with product setup

Standardized Product Descriptions

Formalized Product Descriptions

Domain specific language● problem-oriented● human-understandable● text-based● machine-processable

Use of ConfigModeler at NSN

● Product specialists specify and set upproducts models in SAP

● 20 users (10 regular)● up to now 60 products● but: not a tool for all products

Product Modeling in SAP VC

existing:● textual languages for procedures and constraints● interactive creation and change of VC objects

missing:● human-readable textual language for VC objects

– diff / merge / version control– find / replace– partial models– product model as a document

VCML: DSL for SAP VC

● Simple DSL for SAP VC objectswith embedded languages for procedures and constraints

● DSL design:● Make it simple● Model only important properties of SAP objects,

others are hard-wired or defaulted

VCML Example: Characteristic

characteristic WP_OPTIONS { description "Web Phone Options" documentation "Some long documentation on Web Phone Options" symbolic { numberOfChars 3 values { '001' { description "Cable for connecting monitor" } '002' { description "Voice mail" } '003' { description "Camera" } '004' { description "Additional Antenna" } '005' { description "Memory Upgrade" dependencies { WP_MEMORY_UPGRADE } } '006' { description "Self-Cleaning Screen" } } } status released [ multiValue required ]}

VCML Example: Precondition

precondition WP_MEMORY_UPGRADE { description "Precond. for memory upgrade" status released source {* memory upgrade is only allowed with answering machine$self.WP_options specified and$self.WP_options = '002'. }}

Summary

Product modeling is like programming● Use appropriate languages ● Use appropriate tools

Tool chain for text-based product modeling● CML, VCML:

two languages with different abstraction levels● ConfigModeler, VClipse:

two Eclipse-based IDEs
