High- Level Specification

Functional Overview

 Standard SAP WBS element tables offer foundational fields for project structuring, but they often need to be enhanced for business-specific attributes. Within the Syensqo business solution, some custom fields are introduced to capture critical dimensions such as financial nature (e.g., CAPEX/OPEX), operational context (e.g., Maintenance Event), and legal entity mapping (e.g., Trading Company Code). These fields will enable reporting, better compliance and cross-steam integration.

Scope and Objectives

Scope of the enhancement are-

• To add three new fields to the WBS element master data i.e. CAPEX/OPEX, Maintenance Event & Trading Company Code.
• Enable data entry, validation, and storage in the appropriate database tables.

Objective- Enable additional Syensqo specific fields for classification of WBS elements by financial nature (CAPEX/OPEX), operational context (e.g., Maintenance Event), and legal entity mapping (Trading Company Code).

N/A

Assumptions

• The addition of Z-fields within the standard table structure ensures that standard SAP functionality remains unaffected.
• The newly introduced custom fields will be seamlessly integrated into the SAP user interface across both Fiori and GUI, ensuring consistent availability within project and WBS specific applications and t-codes.

Dependencies

Security, Integrity and Controls

Standard authorization object checks will be applicable to the newly created Z-fields.

Design Rationale

Functional Requirements

The I2M functional design introduces three custom fields to the WBS element master data i.e. CAPEX/OPEX, Maintenance Event, and Trading Company Code to enhance financial classification, maintenance tracking, and intercompany governance.

The CAPEX/OPEX field is mandatory and identifies whether the WBS element is intended for capital investment or expense capture, driving downstream reporting and settlement logic.

The Maintenance Event field is conditionally editable and applicable only to turnaround-specific WBS elements, allowing linkage to predefined maintenance cycles or events.

The Trading Company Code field is mandatory for intercompany recharge projects, ensuring accurate identification of the trading partner for billing and reconciliation.

All fields will be integrated into the WBS master data screen via a custom tab, with validation logic, dropdowns, and field help to support user experience, audit-readiness, and governance compliance.

Proposed Technology to Use

SAP provides for the development of WBS custom fields through in-app extensibility.
