Not at all.
Head over to sap-press.com and you will find good ABAP books.Something like 'ABAP Objects' from Keller and Krüger should help to get started.

Hi, I need to choose a product to monitor server accesses and also database accesses, but to monitor our databases I should start audit on them (so I need to stop and start our database) and collect many transactions just to let that tool to read the DBA_AUDIT_TRAIL table, get those informations over the net, insert them into the tool's database (another Oracle database) and then delete them from our databases... !!!
I've read this thread and also this one ( Oracle Audit Vault vs Third Party Tools )
It seems that with Audit Vault I need to enable audit on all our databases and then it will collect audit informations from a central machine, is it right ? Is there no way to collect those informations, reading them from archivelog or in another way ? How much does audit impact over performances on a OLTP database ?
Instead Database Vault seems to provide ONLY :) strong access control, but it seems it doesn't use AUDIT table... is this right ?
What are pros and cons comparing these products ?

Pre-Requisites for Implementing E Recruiting on ECC6.0

Hi All,
Can anyone please tell me what are the pre-requisites that are to be met to implement E-Recruitment on ECC6.0 (No EHP).
And where can i find out the differences of Erecruitment on ECC6.0 and EHP6 (Functionalities that will be missed if we go without EHP6).
Also is EP necessary to implement E recruitment. We even do not have ESS / MSS
Our System is a Plane ECC (No EHP).
Regards
Syed

Hello Ameen,
Well ECC6.0 is R/3 Server and EHP6 is Portal server .
E-recruitment works good with portal. It provides so may functionalities there .
If u don't have EHP or don't want to use it .
In that case u can Create Customized module pool Application , but obviously u will not get feel and look and some other functionalities available over portal .
You can create Role Matrix table, where u can save roles of Recruiter, manager and id password etc etc .
Plus SAP has also provided traditional Recruitment in R/3 system, you can also use that . You can find that in SPRO .
From EHP4 Sap moved on to Webdynpro abap which was BSP till EHP3 , SO you can also use Webdynpro applications directly without portal . But there you need to customize more . OR you can have Customised Webdynpro application for Recruitment also .
Regards,
Pran

Unicode Compatability is a pre requisite for ECC 6.0

Hi all,
Can any body send me any link or any document which says tht Unicode Compatability is a pre requisite for ECC 6.0. its really urgent.
Regrads,
Ruchika saini

Hi
see this
The Link will be helpful to you.
Re: Upgrade 4.6 to ECC - What are the responsibilites
regarding Unicode influence in Standard programs
Very good document:
http://www.doag.org/pub/docs/sig/sap/2004-03/Buhlinger_Maxi_Version.pdf
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/d37d1ad9-0b01-0010-ed9f-bc3222312dd8

You need to use the transaction UCCHECK.
The report documentation is here
ABAP Unicode Scan Tool UCCHECK
You can use transaction UCCHECK to examine a Unicode program set for syntax errors without having to set the program attribute "Unicode checks active" for every individual program. From the list of Unicode syntax errors, you can go directly to the affected programs and remove the errors. It is also possible to automatically create transport requests and set the Unicode program attribute for a program set.
Some application-specific checks, which draw your attention to program points that are not Unicode-compatible, are also integrated.
Selection of Objects:
The program objects can be selected according to object name, object type, author (TADIR), package, and original system. For the Unicode syntax check, only object types for which an independent syntax check can be carried out are appropriate. The following object types are possibilities:
PROG Report
CLAS Class
FUGR Function groups
FUGX Function group (with customer include, customer area)
FUGS Function group (with customer include, SAP area)
LDBA Logical Database
CNTX Context
TYPE Type pool
INTF Interface
Only Examine Programs with Non-Activated Unicode Flag
By default, the system only displays program objects that have not yet set the Unicode attribute. If you want to use UCCHECK to process program objects that have already set the attribute, you can deactivate this option.
Only Objects with TADIR Entry
By default, the system only displays program objects with a TADIR entry. If you want to examine programs that don't have a TADIR entry, for example locally generated programs without a package, you can deactivate this option.
Exclude Packages $*
By default, the system does not display program objects that are in a local, non-transportable package. If you want to examine programs that are in such a package, you can deactivate this option.
Display Modified SAP Programs Also
By default, SAP programs are not checked in customer systems. If you also want to check SAP programs that were modified in a customer system (see transaction SE95), you can activate this option.
Maximum Number of Programs:
To avoid timeouts or unexpectedly long waiting times, the maximum number of program objects is preset to 50. If you want to examine more objects, you must increase the maximum number or run a SAMT scan (general program set processing). The latter also has the advantage that the data is stored persistently. Proceed as follows:
- Call transaction SAMT
- Create task with program RSUNISCAN_FINAL, subroutine SAMT_SEARCH
For further information refer to documentation for transaction SAMT.
Displaying Points that Cannot Be Analyzed Statically
If you choose this option, you get an overview of the program points, where a static check for Unicode syntax errors is not possible. This can be the case if, for example, parameters or field symbols are not typed or you are accessing a field or structure with variable length/offset. At these points the system only tests at runtime whether the code is sufficient for the stricter Unicode tests. If possible, you should assign types to the variables used, otherwise you must check runtime behavior after the Unicode attribute has been set.
To be able to differentiate between your own and foreign code (for example when using standard includes or generated includes), there is a selection option for the includes to be displayed. By default, the system excludes the standard includes of the view maintenance LSVIM* from the display, because they cause a large number of messages that are not relevant for the Unicode conversion. It is recommended that you also exclude the generated function group-specific includes of the view maintenance (usually L<function group name>F00 and L<function group name>I00) from the display.
Similarly to the process in the extended syntax check, you can hide the warning using the pseudo comment ("#EC *).
Applikation-Specific Checks
These checks indicate program points that represent a public interface but are not Unicode-compatible. Under Unicode, the corresponding interfaces change according to the referenced documentation and must be adapted appropriately.
View Maintenance
Parts of the view maintenance generated in older releases are not Unicode-compatible. The relevant parts can be regenerated with a service report.
UPLOAD/DOWNLOAD
The function modules UPLOAD, DOWNLOAD or WS_UPLOAD and WS_DOWNLOAD are obsolete and cannot run under Unicode. Refer to the documentation for these modules to find out which routines serve as replacements.
Regards
Anji

MOPZ selecting technical usages with JAVA pre-requisite

Hello all,
Upgrading from 46C to EHP5. Some of the desired technical usage require both ABAP and JAVA system. For example, HCM_Learning Solution has the following pre-requisites
- SAP Learning Sol-Client (Lern, Auth, CP) - all JAVA
- Learning Solution (ABAP)
- SAP Learning Sol-Frontend ABAP
- Portal Content (Java)
So cannot select it in MOPZ since the 46C is not connected to a JAVA instance.
It means the ABAP side reqires two-step upgrade (1) upgrade to EHP5 without the HCM_Learning Solution, then (2) connect to a JAVA instance, select it it in MOPZ, then another ABAP upgrade with HCM_Learning Solution.
Any suggestion how to do the ABAP side in single step - i.e. include the Learning Solution (ABAP and the SAP Learning Sol-Frontend ABAP, then just create the JAVA instance after the ABAP upgrade? Is this a valid scenario?
Regards,
Terry

Hi,
Workaround of this situation is:
Add As Java usage type as well in system definition in SMSY. As a result you will be able to select these usage type as well in MOPZ. But it will give you Java packages as well. You can ignore those packages. And then you can carry out upgrade in a single step.
Thanks
Sunny

Pre requisite for Modification

Hi All,
Is there any specific pre requisites for Modification adjustments after prepare mode from abap prespective ?
We need to check these before we do an upgrade on the system from ABAP prespective.
Cheers,
Reddy

Hi All,
Upgrade document shows these are the planning steps need to take care .
Changes to the Translation of an Object Text
The changes are made in the translation environment (transaction SE63) or in the ABAP Workbench. An
SSCR key is not required.
Caution
Changes to translations of SAP objects are not retained when you perform an upgrade. They are
overwritten by a new version or deleted. For more information about retaining these changes, see SAP Note 485741.
Modifications to the Object
You may need an SSCR key to perform the modification adjustment. Get the key before you upgrade the
system. For more information, see SAP Service Marketplace at service.sap.com/sscr.
All modified standard SAP objects are displayed for adjustment in transaction SPDD or SPAU. Objects that
SAP no longer delivers are deleted. If you want to keep these objects, you have to accept the modifications
in transaction SPDD or SPAU.
Caution
Make sure that before the upgrade there is at least one package in the customer namespace (Z*). You
need this package if you have to create objects during the modification adjustment, for example, for an
append structure for customer fields of an SAP table.
You cannot create packages during the upgrade.
I have checked the prerequisites mentioned here .
When i run se95 i get 2 modification adjustments in red color under translations.
It shows there are transacation LSMW
Authorization Objects B_LSMW.
When i double click these two it traverse me to SE63 transaction. Please let me know what i need to check in these two entries in regard to translations.
Please let me what need to take care for these two before i confirm to BASIS team to go head with Upgrade.
Cheers,
Reddy
