Required customer Function Modules

1 Overview of customer Function Modules
2 Required Authorizations in SAP
- 2.1 AAAB - Cross-application Authorization Objects
- 2.2 BC_A - Basis: Administration
3 Developer Key

The Performer Suite is ready to use right after installation, but by using some RFC-enabled customer Function Modules, the list of features can be expanded. In the case of BW Releases 7.4 and higher it is even necessary to use customer Function Modules for the SAP synchronization.

The software provides functionalities to install and update those Function Modules with minimal manual effort in the system.

To use the full potential of the Performer Suite, please install all listed function modules.

Overview of customer Function Modules

#	Function Module	Description	Module
1	Z_RFC_ENTITY_SYNC	Synchronization with SAP objects. If the Function Module is not installed, the synchronization works, but with less performance. (not needed for BW/4HANA)	General
2	Z_RFC_READ_REPORT	Read the Source code of Includes, Reports, and Function Modules.	Docu Performer, System Scout
3	Z_RFC_GET_DTP_DETAILS	Read DTP Filter and Semantic Groups.	Docu Performer
4	Z_RFC_AUTH_CHECK	Identify users who are authorized to Queries. If the Function Module is not installed, this will still work, but with much less performance.	Docu Performer
5	Z_RFC_USAGE_ANALYSIS	Mandatory for Where-Used analysis of InfoObjects and reporting entities. The Where-Used analysis of InfoProvider works also without the Function Module.	System Scout
6	Z_RFC_CODESCAN	Mandatory for a scan of ABAP source code (coding in Transformations, Includes, Methods, DTP Routines, etc.)	System Scout
7	Z_RFC_GET_STRING	Mandatory for table calls where at least one field is of type STRING.	Docu Performer
8	Z_RFC_TRANSLATION	Change descriptions of objects in relevant tables of the SAP BW-System.	Migration Booster, Translation Steward
9	Z_RFC_ADSO_GETDTL_XML	Read information about an ADSO.	Migration Booster
10	Z_RFC_ADSO_CREATE_XML	Create and activate ADSOs in the SAP BW-System.	Migration Booster
11	Z_RFC_FUNCTION_DELETE	Delete Function Modules in the SAP BW-System. Required when updating Function Modules.	General
12	Z_RFC_CHECK_ACT_TR	Check, activate, and assign transports of all object types in the Translation Steward.	Translation Steward
13	Z_RFC_HCPR_CREATE	Create and activate HCPRs in the SAP BW-System. (can only be created if the class 'cl_rso_hcpr_metadata_api' is found in your BW - see SAP Note 2391785)	Migration Booster

The first characters (Z_ default) are a freely selectable prefix that can be changed individually. Unfortunately, the SAP Function Module "FUNCTION_CREATE_REMOTE" supports no technical names which contain "/". If you need this sign (because of own SAP customer namespace), we recommend the following: create the Function Modules simply with Z_ and copy them afterward in SAP in the desired namespace.

Required Authorizations in SAP

You need the following SAP authorizations if you want to install the customer function modules:

AAAB - Cross-application Authorization Objects

S_RFC - Authorization Check for RFC Access [T-B274007000]

Authorizations Field	Values
ACTVT	16 Execute
RFC_NAME	AUTHORITY_CHECK, ENQUEUE_READ, RFC_FUNCTION_DELETE, RFC_GET_ FUNCTION_INTERFACE, RFC_READ_REPORT, RFC_READ_TABLE, RFC1, RFCPING, RPY_INCLUDE_UPDATE, RS_FUNCTION_POOL_INSERT, RS_FUNCTI- ONMODULE_INSERT, SDTX, SEUF, SIFP, SIW_RFC_REPOSITORY, SIW_RFC_WRI- TE_TADIR, SUNI, SUSR, SYST, USER_NAME_GET, Y, Z
RFC_TYPE	FUGR, FUNC

S_SIW_CFG - Authorization for projects in SIW [T-B274007000]

Authorizations Field	Values
ACTVT	02
Config ID	<DUMMY>

BC_A - Basis: Administration

S_TABU_NAM - Table Access by Generic Standard Tools [T-B274007000]

Authorizations Field	Values
ACTVT	03
Table	CVERS, DEVACCESS, E070V, E071, FUPARAREF, INFO_FUNCT, PROGDIR, TADIR, TFDIR, TLIBG

BC_C - Basis - Entwicklungsumgebung

S_DEVELOP - ABAP Workbench [T-B274007000]

Authorizations Field	Values
ACTVT	01, 02, 03, 07, 16 Execute
DEVCLASS	$TMP, , Y, Z*
OBJNAME 1	Y, Z
OBJTYPE	FUNGR, FUNC
P_ GROUP	*

For "DEVCLASS" and "OBJNAME" customer-specific namespaces are required.

Developer Key

For a Dev Key, please check the table DEVACCESS (SAP transaction SE16) for your user name to be found.

The SAP user needs a Developer Key (from your SAP Basis) in the following two cases:

If you want to create new Function Modules or
Update present Function Modules (e.g. after a major release of the Performer Suite)

Onwards SAP Basis Release >= 7.53 (table=CVERS /COMPONENT=SAP_BASIS), we no longer need to check for a developer key (when we create the function modules).
As of SAP Basis 7.53, the authorization object S_DEVELOP is required.
BW/4HANA 2.0 and certain releases of S/4 are then based on an SAP Basis >= 7.53.

If your SAP User cannot be found in the table DEVACCESS, but you received a Dev Key from your SAP basis do the following:

Go to SAP transaction SE80 and start creating a program.
Proceed with the process, until the SAP GUI asks you to enter your Developer Key.
Now, the check of the Function Modules will be successful (no need to restart the Performer Suite).
