Graphical Scheduling in SAP - Problem

Problem Description

Needs

Graphical Representation of Scheduling Data

Simple, intuitive format of data

Links work capacity to scheduling activities

Interactive interface

Dynamic updates and checking with SAP

Useful work order assignment prints

Graphical Scheduling in SAP – IW38

Tabular Report Format - Adjustable Display

Built in Graphical Representation

Refresh Capability

Simple Download to Excel



Disadvantages

Difficult to Schedule

Snapshot Graphical Display

Static, non-interactive

Limited data display

No linking to capacity planning


Standard Gantt Chart Display

Download the data into Excel

Scheduling done in Excel (still no graphical interface)

Data not re-entered into SAP

Performance information is lost

Cost information is lost/disconnected from invoicing

Work orders “forgotten” or “dropped”

Graphical Scheduling in SAP – P3

Option 2 - Export to Scheduler (Primavera)

Advantages

Scheduling is much more robust

Scheduling tools are excellent

Packages are designed specifically for scheduling

Hooks are provided from SAP to tools



Disadvantages (Export Only)

Data is exported only

Performance information is lost

Cost information is lost/disconnected from invoicing

Error checking not available



Disadvantages (Export/Import)

Requires third party integrator

Software (in addition to SAP and Primavera)

Hardware (servers to hold interface engine)

Geared to Project Systems

Link data to PM objects to PS analogs

Additional work required for linking

* Impress software is doing pilot at Valero



In Practice

Export to Primavera used

All scheduling performed in Primavera

SAP scheduling data is inaccurate

SAP data cannot be re-exported without date conflict

SAP work orders only hold invoice/cost data

No relations to scheduling dates
