" The role of the update work process is very important since it is responsible for recording the changes in the database. The process performs its functions when the ABAP applications are programmed with the statements in the UPDATE TASK. This type of updating is asynchronously performed, ie. The programs leave update records in a queue to be processed and then continue to the update process. Normally, it runs without any intervention from the SAP R/3 management, still R/3 includes utilities to monitor check and perform management operations on the updation processes. In case any updating error takes place, the system places a message to the user regarding the error and an alert is triggered in the CCMS monitor. For the update functions go to Administration menu bar option --> Monitor option ---> Update option. An initial update screen showing various functions appears. The initial update screen is used to display the system update records with error status or the records which have not yet been processed, activate and deactivate the updating in the whole SAP system. It is also useful to display the update statistics, to display the data on the erroneous update records and reprocess them, either in real or in test mode and to send waiting update records for processing after a deactivation/activations of the updating and delete update records. Many work processes of the type R/3 system update the database. A database interface is included by the dialog and background work processes, which can directly update the database. However, the update work processes ca also be used for updating the physical database in asynchronous way. If it is asynchronous updating, according to which the transactions are programmed in the ABAP business applications, then in the database commit phase, the transactions pass the update records to the update work processes."
"Radio Frequency Identification Devices are responsible for electronically capturing the data related to Materials. Once the data is captured, it is transmitted via Radio waves to the SAP server. The main use of RFID devices is in Warehouses where the data is physically moved from one location to another. It is very convenient for the warehouse personnel to make use of RFID so that all the material movement is captured automatically and the information is transferred to the SAP server. SAP Auto-ID Infrastructure is the component in SAP Netweaver that provides gateway to the RFID Data."
If you wish to Lock or UnLock a program Editor Lock it can be done by the program given below. The SAP System Table TRDIR has a field called EDTX which is basically the EDITOR lock filed. Edit Lock facility is given in the PROGRAM ATTRIBUTES. The EDITOR LOCK is a check box given in the PROGRAM ATTRIBUTES. If this field is SET then the program gets locked and if this is Unchecked the the program is unlocked.
If the EDITOR lock is ON then only the program's author user who has created the program can edit it. Please find the program below.
A logical database can be used in the following ways.
By linking it was an executable program in Program Attributes. By using the function module LDB_PROCESS
The SELECTION SCREEN is displayed only if link the Logical Database in the Program Attributes. It is not displayed if you call it using the Function Module LDB_PROCESS.
Editing Logical Databases:
The Logical Database can be edited using the following methods.
By using the Logical Database Builder in ABAP workbench. Transaction SE36 or SLDB the menu path is given below.
Tools---------->ABAP Work Bench--------------->Development------------->Programming Environment-------------->Logical Database Builder
Naming the Logical Database: The name can be upto 20 characters. It can also contain a three to to ten character namespace prefix, enclosed in forward slashes. From the initial screen the Logical Database can be created, copied or deleted. Before deleting the Logical Database its links form any program should be removed. You can use the where used link to find exactly where a Logical Database used before deleting it.
If you wish to edit a Material, you can use the following BAPI.
BAPI_MATERIAL_EDIT
The above mentioned BAPI makes use of CALL TRANSACTION MM02 or MM42 to edit the MATERIAL. The selection of the appropriate transaction is made based on the entered material. The table MAW1 is checked for the existence of material, if the material exists in MAW1 then the transaction MM02 is called else transaction MM42 is called.
BAPI_MATERIAL_EDIT in turn calls the following function modules.
BAPI_MATERIAL_EXISTENCECHECK and CONVERSION_EXIT_MATN1_OUTPUT
The user is then presented with the change material screen either for MM02 or MM42.
The code below shows the values of the input parameters for the BAPI BAPI_MATERIAL_EDI
REPORT ZEX_CHANGEMAT .
Parameters: p_matnr like BAPIMATALL-MATERIAL, p_fscrn like BAPIMATALL-SKIP_1ST_SCREEN.
Data: d_ret like BAPIRET1.
CALL FUNCTION 'BAPI_MATERIAL_EDIT' EXPORTING MATERIAL = p_matnr SKIP_1ST_SCREEN = p_fscrn IMPORTING RETURN = d_ret .

SAP Standard Programs can be easily modified/changed using Business Add-Ins or BADIs. And all this can be done without any system level modifications. Business Add-Ins are a new SAP enhancement technique based on ABAP Objects.
BADIs are based on ABAP objects and are new techniques introduced by SAP for changing the SAP Standard programs as per the user requirements. The concept is similar to User Exits but BADIs make use of ABAP Objects. Many industries have some specific requirements that may not be configurable in SAP. This can be easily achieved using BADIs. The original Object does not change as this piece of code is inserted in specific points using BADIs.
Go To IMG( Implementation guide) Transaction SPRO.
Find the BADI in implementation Guide (IMG)
Search for BADI Check the Documentation For BADI for functionality
Functionality will be implemented in the Method.
Business Add-Ins can be defined according to filter values. This allows you to control add-in implementation and make it dependent on specific criteria.
User Exits / Enhancements use Transactions SMOD/CMOD. See also: User Exits in SAP
Always specify your conditions in the Where-clause instead of checking
them yourself with check statements. The database system can then use an index
(if possible) and the network load is considerably less.
Always use Pretty Printer and Extended Program Check before releasing the code.
Do not leave unused code in the program. Comment the code thoroughly. Align the comments and the Code. Follow the SAP Standards and SAP Best Practices guidelines. It’s a good practice to take a dump of the code on your local drive.
