EIM Delete Process Overview

This process deletes the records from the Siebel base tables.
Deletes records from the base table by identifying the records in the base on the basis of the user keys specified in the corresponding interface table.
Deletes all records from the Siebel base table if the parameter DELETE ALL ROWS is specified as true. For this process the records are not populated in the interface table. Even if the records are populated on using this parameter EIM component skips these records and proceed by deleting all the rows in the given base table
If the DELETE MATCHES parameter is specified then only those records are deleted that matches the condition in the WHERE clause.
On successful deletion the IF_ROW_STAT column of the interface table will have the status as DELETED.

This process allows to pull the existing records from the Siebel base tables.
The interface table need to be correctly identified.
Create the configuration file with suitable parameters as in EXPORT ALL or EXPORT MATCHES according to the requirement
Start the EIM job manually by logging into the application and navigating to Administration – Server or via the command line.

The process drives the new record inserts and updates on existing records in the Siebel base table.
The interface table need to be correctly identified.
Load the business data into the identified interface tables.
Create the configuration file.
Set the value of IF_ROW_STAT to FOR_IMPORT before load.
Make sure all the user key columns and the required columns for the targeted base tables are populated in the corresponding columns mapped in the interface tables.
Start the EIM job manually by logging into the application and navigating to Administration – Server or via the command line.

An Overview to EIM Process

There are four types of process in EIM. They are :-

Import Process.
Export Process.
Delete Process.
Merge Process.

Import Process

Import Process is basically used to Insert or Update the data from external system into the Siebel base tables.
Identify and validate the data to be imported.
Identify the column mappings and user key columns of the data to be imported.
Import the data in the order of the business model.
Set the value of IF_ROW_STAT to FOR_IMPORT before load which will get changed to IMPORTED after process successfully commits.

Merge Process Parameters in IFB

These are the parameters which are only applicable to EIM Merge process and are written with in the Process section in an IFB file used for merge process. They are :-

SET BASED LOGGING

This parameter specifies whether to enable the set based logging.
When enabled, a separate log entry will be generated for all the rows in each table that were processed by EIM. This allows greater performance.
When disabled, each and every row processed by EIM will have an entry in the transaction table.
Valid values are TRUE or FALSE.
Default value is TRUE.
Example: SET BASED LOGGING = TRUE

Delete Process Parameters in IFB

These are the parameters which are only applicable to EIM Delete process and are written with in the Process section in an IFB file used for delete process. They are :-

CASCADE DELETE ONLY

Optional parameter that tells whether to delete the child records when a parent record is deleted.
Valid values are TRUE or FALSE.
Default value is FALSE.
If set to FALSE, EIM deletes the parent record and sets the foreign key column in the child records to NULL.
Example: CASCADE DELETE ONLY = TRUE
