SAP System RefreshProcedure Document

for SAP R/3 onWindows/Oracleplatform.This document outlines how to refresh an SAP R/3 4.6C system on Windows/Oracle

platform.

The acronyms used in documents are

bp1tulap130 = Target DB

Prerequisites:1. Windows login access on Host

2. Checking OS level configuration i.e. adm, ora users, environment

variable settings

3/21

2. Execute a user master export of PFM client 100.

Go to transaction SCC8 (client export)

Choose the following,

Profile: SAP_USER

Target System: PFM

Click on Start Immediately

Take note of the request number.

If above method does not work do the following.

TP pf=TP_DOMAIN_PSM.PFL export client 100 UI

(example of transport #: PFMKT00140, note T not 9)

3. Execute table export of PFM client 100.

Map \\\e$ to Z: drive on Ensure the scripts

export_pfm_tables.cntl and import_pfm_tables.cntl Conatins all the client dependent and

client-independent tables listed below.
