Difference between EIT and SIT

The main difference between Special Information Types and Extract Information Types is that SIT is KeyFlexfield whereas EIT is Descriptive Flexfield.

What does this mean for your implementation?

In the context of SIT being KFF, you attach a combination of attribute values to a Person Record.

Let's take an example.

Say we have a requirement to capture two fields against a Person

Field 1 :- Smoker Yes/No

Field 2:- Colour Blind Yes/No

In case of SIT, assuming there are two non-smokers and neither of those are colour blind, then there will be just one record in table PER_ANALYSIS_CRITERIA

Segment1 = N

Segment2 = N

ANALYSIS_CRITERIA_ID=1000

For both these people, their respective SIT records in PER_PERSON_ANALYSES will reference "ANALYSIS_CRITERIA_ID=1000"

Think of this like CODE_COMBINATION_ID in GL_CODE_COMBINATIONS, and compare that to PER_ANALYSIS_CRITERIA

However in case of EIT, assuming same example as above, two physical records will be created in table PER_PEOPLE_EXTRA_INFO

PERSON_ID     PERSON_EXTRA_INFO_ID      PEI_INFORMATION1      PEI_INFORMATION2

-----------    ------------------------     -------------------      --------------------

104332           100000                        N                                  N

104332           100001                        N                                  N

Should my decision be based upon saving space in the database, so that records can be reused in case of SIT?

Not really, space is hardly an issue these days in ERP systems, few bytes here or there make no difference at all to database sizing.

However there are other differences that can be considered in making this decision.

Updates made to SIT's are less efficient

In this example, if a person were to become a Smoker from non-Smoker, then, when you update persons SIT record, Oracle will query PER_ANALYSIS_CRITERIA to check if a combination of Y[smoker] and N[Colour Blind] already exists in that table. If such record combination is not found, then Oracle will create such combination in PER_ANALYSIS_CRITERIA. Following that record creation, PER_PERSON_ANALYSES will be updated to reflect the new ANALYSIS_CRITERIA_ID for Y & N combination.

However in case of EIT, Oracle would have to merely update the PER_PEOPLE_EXTRA_INFO table.

During implementation, when deciding between EIT and SIT, should I ask myself a question that- how often will Extra Information be modified?

Indeed, given that columns segment1, segment2.....segment30 in PER_ANALYSIS_CRITERIA are not usually indexed [unlike in gl_code_combinations]

At what Levels do EIT work?

However in case of SIT's, those are usually defined at Person Level [although these SIT can be enabled at Job/Position level too].

PER_PERSON_ANALYSES table has date_from and date_to. Does this mean a SIT Combination for a person can be end-dated?

Correct, you can implement a date-track kind-of model with SIT [not true date-tracking though, as inactive record are displayed in screen too]

However in case of EIT, in order to implement a similar logic for date ranges, you will have to use PEI_INFORMATION1 to capture DATE_FROM, and use PEI_INFORMATION2 to capture DATE_TO

However Security model of SIT differ from that of EIT?

The security model of EIT is more advanced than SIT.

If an SIT is made available to responsibility via Taskflow, then all the Special Information Type Contexts[ SIT KFF Contexts] will be available to the user.

See link Basics of Special Information Types to see the steps for defining and enabling SITs in Oracle HRMS.

Security of EIT is a two step process

Step 1 for EIT Security :- Register EIT for its usage in a specific Legislation Code

To make an EIT visible for a given Legislation, a record must be entered in EIT registration table for LegislationCode & EIT combination[see the pl/sql procedure at the bottom of this article to see list of those table]. Instead of executing the procedure below, you may decide to run concurrent program "Register Extra Information Types (EITs)"

Step 2 for EIT Security :- Make the registered EIT available to specific Responsibility using screen "Information Type Security"

PL/SQL Code in case you wish to register EIT using SQL
