Short description on bdc

Question

Hi
ABAP GURU'S.
PLZ give short discription of Recording screen field name in BDC.
1-What are the meaning and use of Local, synchronous, asynchronous update mode.
2- What is the full name of CATT MODE and dscribes these mode.
NO CATT.
Catt without individual screen control.
Catt with individual screen control.
What is the default size in BDC.
Describes count after commit.
Describes not a batch input session.
Describes simulate background mode.
What are the Table Control in BDC.
Plz give reply immediately.

Answer 1

hi
hope it will help you.
reward if help.
RECORDING A BATCH INPUT
A B recording allows you to record a R/3 transaction and generate a program that contains all screens and field information in the required BDC-DATA format.
You can either use SHDB transaction for recording or
SYSTEM ? SERVICES ? BATCH INPUT ? EDIT
And from here click recording.
Enter name for the recording.
(Dates are optional)
Click recording.
Enter transaction code.
Enter.
Click Save button.
Asynchronous Update – The program does not wait for the work process to finish the update. Commit Work.
Asynchronous updating. In this mode, the called transaction does not wait for any updates it produces to be completed. It simply passes the updates to the SAP update service. Asynchronous processing therefore usually results in faster execution of your data transfer program.
Asynchronous processing is NOT recommended for processing any larger amount of data. This is because the called transaction receives no completion message from the update module in asynchronous updating. The calling data transfer program, in turn, cannot determine whether a called transaction ended with a successful update of the database or not.
If you use asynchronous updating, then you will need to use the update management facility (Transaction SM12) to check whether updates have been terminated abnormally during session processing. Error analysis and recovery is less convenient than with synchronous updating.
Synchronous Update – The program wait for the work process to finish the update. Commit Work and Wait.
Synchronous updating. In this mode, the called transaction waits for any updates that it produces to be completed. Execution is slower than with asynchronous updating because called transactions wait for updating to be completed. However, the called transaction is able to return any update error message that occurs to your program. It is much easier for you to analyze and recover from errors.
L Local updating. If you update data locally, the update of the database will not be processed in a separate process, but in the process of the calling program. (See the ABAP keyword documentation on SET UPDATE TASK LOCAL for more information.)
CATT
SAP users use CATT frequently to upload master data or to make changes to master data records. SAP Consultants and Abapers tend to use it for creating test data. The transactions run without user interaction. You can check system messages and test database changes. All tests are logged. The CATT records your keystrokes while performing the actual transaction. You then identify the fields that you wish to change in that view. Then export this data to a spreadsheet to populate with the data required. This is uploaded and executed saving you keying in the data manually.
To perform CATT, it has to be enabled in your production environment (your systems administrator should be able to do this - SCC4). You will also need access to your development system to create the CATT script.
The process of uploading data with a CATT:
Activate CATT in your client
In transaction code SCC4 - click the change button
Double click on the client number
In the Restriction section, tick Allows CATT processes to be started.
Upload data using CATT
1. Create Import variant for the fields you need
Transaction SCAT
Goto Parameters
Create Import Variant
Goto Variant -> Edit
Goto Variant -> Fast entry or F9

2. To change the MRP Group for a list of Material
Assuming that I want to change the MRP Group for a list of Material.
My text files should look something like this:
[Variant ID] [Variant Text] &ZDISGR &ZMATNR
--> Parameter texts MRP group Material
--> Default Values M1 A001
Changes to the default values displayed above not effective
#01 M1 A001
#02 '' A002
#03 M1 A003
Note : '' denotes a blank in the field. e.g. Material A002 MRP group will be replaced by a blank.
3. Configure the recorded entry fields to read from the imported text file data
In the CATT : Maintain functions test case Screen
Double click on the Object Name
Double click on the screen number with your desired fields
Park the cursor on the fields
Click Edit -> Details
Fill in the Parameters Name and Field Contents
Finish Save it.
Assign your text file data.
In the CATT : Execute test case Screen
Click External from file and choose your text file
CATT will now read from your text file and update whatever data you have specified.
