Issue/Introduction

At the Target Definition creation stage during Target mapping it is sometimes discovered that the target tables don't currently exist. This is evident when the target names are entered when the "Map" column changes from YES to NEW. This means that the table does not exist or was not found by that name. The target table needs to be created if the name is the correct one.

Resolution

To create the target table the "T" for Template line command is entered in the "C" column on the far left of the Target Mapping screen next to the source table name.

The template command takes you to the CA RC/Update Table Template screen in order to create the new table. The target table information that was entered has been copied into the screen along with the tablespace and database information from the source table for convenience as well as all the columns from the source table and the other source table attributes.

These can then be changed if required and when ready the PF3 key can be pressed to generate the DDL. When the DDL is displayed it can be submitted online or the EDIT command can be used to further edit the code before execution.

  SET CURRENT SQLID = 'authid';

CREATE  TABLE authid.TBROLE4
        ( ROLE_ID CHAR ( 6 ) NOT NULL
          FOR SBCS DATA
        , ROLE_DESC CHAR ( 50 ) NOT NULL
          FOR SBCS DATA

        )
        IN DBCORP.TSROLE2
   CCSID         EBCDIC
   ;

    SET CURRENT SQLID = USER;

Return to the Target Definition screen using PF3 when the DDL has been executed successfully.

The above table has a primary key so a unique index is needed before data can be loaded to it. The index can be created from the Target Definition screen using the RCU command which will transfer to RC/Update so that an index can be created on the table. 

Command ===> RCU

After that is completed the user is returned to the Target Definition screen. The table will be ready to be loaded now and the target definition can be saved.

Choosing a load option on the target definition....

I - INSERT ROWS USING TARGET DEFINITION

The execution shows the new table being loaded:
