A multiple line field is a special kind of field which allows the user to enter multiple lines of data into it.
The data in BDC tables is saved by using the field name ‘BDC_OKCODE' and field value of ‘/11'.
The first step in a BDC session is to identify the screens of the transaction that the program will process. Next step is to write a program to build the BDC table that will be used to submit the data to SAP. The final step is to submit the BDC table to the system in the batch mode or as a single transaction by the CALL TRANSACTION command.
No. The CALL TRANSACTION method allows only a single transaction to be processed by SAP.
To populate data into a multiple line field, an index is added to the field name to indicate which line is to be populated by the BDC session (Line index).
In all BDC tables the last entry is to save the data by using the field name BDC_OKCODE and a field value of ‘/11'.
The information on the current screen can be found by SYSTEM STATUS command from any menu.
