First Preparation Steps

All Code Page Configurations

Steps When You Start to Prepare the Non-UC System (Part I)

Start Transaction SPUMG

SPUMG provides a set of database scans as tabstrips. Before you run the first scan you might want to read SAP Note 1096903  which provides information about how to split very large tables before scanning them. Then you check the consistency of the non-Unicode database with the first scan in transaction SPUMG:

 

The Consistency Check

In Single Code Page systems this is the only available scan. In MDMP systems there are a couple of other scans which are described in section Advanced Preparation Steps

Read the information on the entrance screen 'Welcome to SPUMG' and process the steps described there. Once you are finished with the first steps, the SPUMG main screen will be opened. Run the Consistency Check now until it is finished completely.

 

After the Consistency Check

The conversion preparation for Single Code Page system is nearly done whereas MDMP systems need more scanning. Please follow the Documentation and Troubleshooting for details about the final preparation steps in Single Code Page systems.

To get an overview of the SPUMG preparation steps for MDMP systems, see section Advanced Preparation Steps

Steps You Can Start With Months Before the Conversion

Check software requirements and keep your system up-to-date

Download the applicable Unicode Conversion/System Copy/Upgrade etc... documentation. Check required software versions (support packages, kernel patches) and apply the latest support package and kernel patch. Use the latest R3load version when starting conversion project
Keep used software stable during conversion project if not advised differently from SAP support.

 

Textflag Handling

All LANG fields in Data Dictionary (DDIC) objects which are delivered by SAP have an attribute Text Lang. (indicator for a language field). This indicator specifies that the LANG field determines the code page of the character data in that table. Ensure that customer objects have this attribute set as well (see Unicode Conversion Guide, chapter Text Language for customer objects.)

 

Reduce Data Volume

Data which has been archived or deleted means less preparation workload and shorter system downtime. In the Unicode Conversion Guide you will find automatic methods and manual steps and links to other documents, for example the Data Management Guide (SMP login required) and SAP Note 679456.

 

Unicode Enabling of ABAP Programs

Make sure your own ABAP programs and SAP programs you modified are adapted to Unicode syntax and runtime restrictions. Follow the workshop slides: Make your own ABAP programs Unicode enabled .
