Is it wise to convert to an SAP NetWeaver EP/XI career from a Java/J2EE background?
I have approximately two years of experience with Java/J2EE. Recently I received a job offer from a company, but the work will include SAP NetWeaver EP and XI. Is it wise to shift from Java to SAP NetWeaver based on this information?
You will be using some Java/J2EE. EP especially uses lots of J2EE. Also, I think you will earn more money in the SAP world if you were to convert.

How do I avoid running ABAP programs more than once?
There is another way to avoid an ABAP program running more than once, without using the function ENQUEUE_ESINDX? If there is, can you tell me how?
If ENQUEUE_ESINDX causes you problems, why not create your own lock object and use that? I've not encountered the use of this particular FM for locking program runs.
What are some ABAP development resources?
| QUESTION POSED ON: 01 September 2006 I have read white papers that claim ABAP development programs need to be object oriented. I have looked for decent examples, but have not found anything except for snippets. I have the ABAP Controls Technology book and Design Patterns in Object Oriented ABAP. I mostly write large table update programs, for example to update the materials or BOM tables using BAPIs or BDCs. I have looked through the demos and examples within SAP, but still have not found anything I thought appropriate for the type of mass-updating programs I write. Design Patterns is interesting but of course it is a dialog program with lots of user interaction. Do you know where I can find decent examples of batch processing programs which use and take advantage of classes, methods, inheritance, implementation, and events; i.e., the concepts that fully use the OO advantages? |

Miscellaneous sap abap faq
1. Can you create a table with fields not referring to data
elements?
YES. eg:- ITAB LIKE SPFLI.here we are referening to a data object
(SPFLI) not data element.
What are the different types of data dictionary objects? tables,
structures, views, domains, data elements, lock objects, Match code
objects.
2. What should be the approach for writing a BDC program?
STEP 1: CONVERTING THE LEGACY SYSTEM DATA TO A FLAT FILE to
internal
table CALLED "CONVERSION".
STEP 2: TRANSFERING THE FLAT FILE INTO SAP SYSTEM CALLED "SAP
DATA
TRANSFER".
STEP 3: DEPENDING UPON THE BDC TYPE
i)call transaction(Write the program explicity)
ii) create sessions (sessions are created and processed.if success
data will transfer).
3. What are the problems in processing batch input sessions and How
is batch input process different from processing online?
PROBLEMS:
i) If the user forgets to opt for keep session then the session will
be automatically removed from the session queue(log remains).
However if session is processed we may delete it manually.
ii)if session processing fails data will not be transferred to SAP
database table.
4. What does an extract statement do in the ABAP program?
Once you have declared the possible record types as field groups and
defined their structure, you can fill the extract dataset using the
following statements: EXTRACT. When the first EXTRACT statement
occurs in a program, the system creates the extract dataset and adds
the first extract record to it. In each subsequent EXTRACT
statement, the new extract record is added to the dataset EXTRACT
HEADER. When you extract the data, the record is filled with the
current values of the corresponding fields. As soon as the system
has processed the first EXTRACT statement for a field group , the
structure of the corresponding extract record in the extract dataset
is fixed. You can no longer insert new fields into the field groups
and HEADER. If you try to modify one of the field groups afterwards
and use it in another EXTRACT statement, a runtime error occurs. By
processing EXTRACT statements several times using different field
groups, you fill the extract dataset with records of different
length and structure. Since you can modify field groups dynamically
up to their first usage in an EXTRACT statement, extract datasets
provide the advantage that you need not determine the structure at
the beginning of the program.
5. Can a transparent table exist in data dictionary but not in the
data base physically?
NO. TRANSPARENT TABLE DO EXIST WITH THE SAME STRUCTURE BOTH IN
THE
DICTIONARY AS WELL AS IN THE DATABASE,EXACTLY WITH THE SAME
DATA AND
FIELDS.
6. What is the step by step process to create a table in data
dictionary?
step 1: creating domains(data type, field length, range).
step 2: creating data elements(properties and type for a table
field).
step 3: creating tables(SE11).
7. What is the typical structure of an ABAP/4 program?
HEADER ,BODY,FOOTER.
8. A situation: An ABAP program creates a batch input session. We
need to submit the program and the batch session in back ground. How
to do it?
go to SM36 and create background job by giving job name, job class
and job steps (JOB SCHEDULING)
9. What are the domains and data elements?
DOMAINS : FORMAL DEFINITION OF THE DATA TYPES.THEY SET
ATTRIBUTES
SUCH AS DATA TYPE,LENGTH,RANGE. DATA ELEMENT : A FIELD IN R/3
SYSTEM
IS A DATA ELEMENT.
10. What is the alternative to batch input session?
Call transaction.
12. What is a batch input session?
BATCH INPUT SESSION is an intermediate step between internal table
and database table. Data along with the action is stored in session
ie data for screen fields, to which screen it is passed, program
name behind it, and how next screen is processed.
13. What is the advantage of structures? How do you use them in the
ABAP programs?
Adv:- GLOBAL EXISTANCE(these could be used by any other program
without creating it again).
14. How many types of tables exists and what are they in data
dictionary?
4 types of tables
i)Transparent tables - Exists with the same structure both in
dictionary as well as in database exactly with the same data and
fields. Both Opensql and Nativesql can be used. ii)Pool tables &
iii)Cluster tables - These are logical tables that are arranged as
records of transparent tables. one cannot use native sql on these
tables (only open sql).They are not managable directly using
database system tools.
iv)Internal tables - .?
