What is the difference between BDC and Call Transaction?

There are certain ways to transfer data. This data transfer can go from an internal table to a database table. This is done through sessions. There are two different kinds of transfers, and they are called BDC Call Transaction and the Session Method of BDC. The session method of BDC has data that is not updated in the database tables. The Subic is returned.

The error log is made for the error records, and the database table is always updated synchronously. The Call transaction method has immediate updating. This takes place in the database. This always occurs except within the session processed table. The error will be handled explicitly, and the database table is updated asynchronously. These are the differences between the BDC and Call Transaction.
