processing is done by asynchronous.

updation done by synchronous?

hi,

Processing: data is processed through transactions i.e. it will validate the fileds and values.

Updation:

data will be updated in the database through transactions.

synchronous Update - It will update transaction level and it goes database level.

then it goes next record.

Asynchronous Update : it will update transaction level and lt goes next record.

later it updates database level.

Synchronous update is slow processing

Asynchronous update is speed processing.

when you update the data at transaction level and it should update the data with respect to corresponding tables .. when you use asyn or syn ,all are sme but only thing is Syn update is it update the record transaction level and it goes db level and it will go next record.

where as Asyn update ,it updates transaction level and it goes next record.but it updates DB Level later.

Hi,

Updation means datbase updation and processing means screen processing.

This mean screen can be process in synchronous or asynchronour way but data base will always update in synchronous manner.

See link

http://www.sap-img.com/abap/difference-between-batch-input-and-call-transaction-in-bdc.htm

To sum up,

In session method- Asynchronous processing - Transfers data for multiple transactions - Synchronous database update During processing, no transaction is started until the previous transaction has been written to the database. - A batch input processing log is generated for each session - Sessions cannot be generated in parallel

Thanks

hi,

Processing means Move data from Internal table(it holds the flat file data) to BDCDATA after perform validations on legacy data.

for this we use two subtoutinees.(mapping logic)

Updation means transfer data from BDCDATA table into Undarlying related Tables through Transaction.
