Iam updating 10 records . I had an error in 5 th and 8th record .

Will the remaining records get updated in session method.

What happens in call transaction method.

We need to process only error records or all records again in session method.

hi jeeven,

in session method by default it can maintain log(error) file, that u can see in t.code 'sm35',

select your session name ->(which u have given in Function module 'BDC_OPEN_GROUP' under group parameter.)

process->

then u can able to see the error records remaining all can updated in database.

if it's call transaction method then you should maintaion log file structure called BDCMSGCOLL.

regards..

hi,

Session method.

error log is created

data is not updated until session is processed.

from the error log we can update the 5 th and 8th record .

<u><b>Call transaction.</b></u>

errors need to be handled explicitly

data is updated automatically

For Update you have

A - asynchronus - does not wait for next update in the queue

S - Synchronus - waits until the previous update is completed before a new request is considered

L - Local update - Uses a different work process to trigger call function in update task.

In synchronus method until one record process takes place into database next record will not be processed.

In asynchronus immedate updation of data into database table.

Check this link for more detailed information:

http://fuller.mit.edu/tech/sync_asynchronous.html

'A', 'S' and 'L' are the update modes in CALL transaction method.

I will give you a simple example to explain this.

Suppose that there are 30 records in total and an error has occured in the 5th record.

In asynchronous, update is done for every 30 records while in synchronous one,

update is done only upto the 4th record.

So only after the record in the fifth one is eliminated, remaining others are processed.
