CHANGING PACKAGE NAME

In the initial ABAP learning periods, I had faced the difficulty of transporting the Table

data from one system to another. I had to MANUALY copy, Master data from onesystem to another; as was unaware of this feature in SAP, that allow us to transport the

data/table contents automatically from one system to another.

Transport Request with Table Contents Attached

Lets check out the steps for the same.

Content of a table can be transported from Development to Quality and to Productionusing Transport System. First you need to attach the table entry to a transport and then

same procedure applies as in case of transporting abap changes.

Step 1: Open the content of table which you want to transport using transaction SE11.

Select Transport Entry from menu.

Select Transport Entries

Step 2 : If you already have a transport then enter in Request input otherwise click on

new button to create transport and follow normal procedure of creating new Request

and attach data to this new Request.

Create a Transport Request

Now if you see the transport in SE09 you will find that table content were attached to

transport. Follow the regular transport procedure to transport these table contect further in

your SAP landscape

ABAP prgrammer sometimes do workout on things locally (Technically, making theobject Local in nature). After all the changes done to the object, the object is ready to

transport to the next landscape for further testing.

Following steps defines how an ABAPer can reassign the Transport Package to the

Object to be transported.


3/15

In this case, lets say, we want to reassign the package to an ABAP program. Following

steps defines how to reassign the Package from Local to Transportable.

1. In SE38, enter your program name.

2. Use the menu option goto -> object directory entry.

3. Click on Change, and you can enter the new package. Youll be prompted for aworkbench request number also. The same technique can be used to change packages in

other objects.

You can also use transaction SE03 (or the tools option from SE09/SE10), but access issometimes restricted.

CUSTOMIZING SAP LOGIN SCREEN

2. Refer to SAP Note 205487 for more on displaying text on login screen.

LOCK OBJECTS IN SAP

Lock objects are use in SAP to avoid the inconsistancy at the time of data is being

insert/change into database.

SAP Provide three type of Lock objects.

- Read Lock(Shared Locked)

protects read access to an object. The read lock allows other transactions read accessbut not write access to the locked area of the table

- Write Lock(exclusive lock)protects write access to an object. The write lock allows other transactions neither read

nor write access to the locked area of the table.

- Enhanced write lock (exclusive lock without cumulating)works like a write lock except that the enhanced write lock also protects from further

accesses from the same transaction.

Type of Locks

Steps:

Go to SE11 transaction and create a lock object for the table .Custom lock object

name should be start with EY or EZ.


12/15

Lock Object - Initial Screen

After activating lock object Function Module will be generated automatically.

Function Modules name will be like ENQUEUE_ and

DEQUEUE_.


13/15

Lock Modules

For Example:

For example you have created a lock object EZSFLIGHT for the SFLIGHT table .

So first lock the table , then update then release the lock.

Check this code

DATA : t_itab like table of SFLIGHT,

fs_itab like SFLIGHT.

fs_itab-carrid = AA.

fs_itab-connid = 0017.

.

.

.

APPEND fs_itab TO t_itab.

.

.

.

CALL FUNCTION ENQUE_EZSFLIGHT SET lock to the table

EXPORTING

CARRID = .

CONNID = .

.

.


14/15

IF sy-subrc eq 0.

INSERT sflight from table t_itab. Update the DB table

ENDIF.

CALL FUNCTION ENQUE_EZSFLIGHT Unlock the table

EXPORTING

CARRID = .

CONNID = .

.

SEARCH TRANSACTIONS BY TEXT IN SAP

Most of the ABAPer or who ever use SAP at some point stuck at the point to know or

remember Transaction codes.

Initial Screen of SAP provided standard T-Code for search

SAP given a simple Transaction code SEARCH_SAP_MENU which accepts text andgives the result input in all Transaction codes which are matched to that particular text.


15/15

Program Ouput

It even provides the details of all the preceding nodes to look at the path (from SAP

initial screen Navigation).
