CO-OM – Enhancing Line Items Report with COOMEP01

Introduction

The analysis of line items is really common for CO and PS Objects and SAP system provided us transaction codes to analyze these documents items for all objects that we can find in CO and PS. Follow most used transaction where you can be familiar with them:

Cost centers	KSB1 – KSB2
Orders	KOB1 – KOB2 – KOB4
Projects (and networks)	CJI1 – CJI3 – CJI4
Cost objects	KVBI – KVBO – KKCS – KRMI
Business processes	CPB1 – CPBP

It is also common to receive user request to improve these information such as authorization control, new columns on these reports, etc.

The Enhancement COOMEP01 – CO-OM: Information system -> line item reports was defined by SAP to help us with these requirements.

You can find a list of 9 function modules for different purposes:

For better understand of these components, let´s group them by category and needs and we can defined that using the following question: WHAT you need to do and WHERE you need to do:

		WHERE
WHAT		Actual Line Items	Plan Line Items	Commit Line Items	Budget Line Items
	Add or Change report information	001	002	003	004
	Perform additional authorization check	005	006	007	008
	Change the output list	009	009	009	009

Example

For example, an user requested us to add the receiver WBS of a transfer budget in budget in CJI1 transaction code report.

Answering previous questions to identify which component we should use to attend this requirement:

WHAT: Add information (receiver WBS of a transfer budget)

WHERE: CJI1 – Budget Line Items Report

So, we could use enhancement component EXIT_SAPLKAEP_004 to attend this business requirements.
