Error Analysis and Restart Capability

Unlike "classical" batch input processing using sessions, CALL TRANSACTION USING processing does not provide any special handling for incorrect transactions. There is no restart capability for transactions that contain errors or produce update failures.

You can handle incorrect transactions by using update mode S (synchronous updating) and checking the return code from CALL TRANSACTION USING. If the return code is anything other than 0, then you should do the following:


write out or save the message table
use the BDCDATA table that you generated for the CALL TRANSACTION USING to generate a batch input session for the faulty transaction. You can then analyze the faulty transaction and correct the error using the tools provided in the batch input management facility.

20) USING CALL DIALOG WITH BATCH INPUT:

A program that uses CALL DIALOG to submit batch input should perform the following steps:

1. For the screens you want processed, fill all desired fields.
2. Use a CALL DIALOG statement to call the dialog module and to pass it to the BDCDATA table.



The MODE parameter in the CALL statement is explained in Using CALL TRANSACTION USING for Batch Input(19).

Example

CALL DIALOG 'DIALOG1' USING BDCDATA MODE 'E'.


(21) DIRECT INPUT:

To enhance the batch input procedure, the system offers the direct input technique, especially for transferring large amounts of data. In contrast to batch input, this technique does not create sessions, but stores the data directly. It does not process screens.

To enter the data into the corresponding database tables directly, the system calls a number of function modules that execute any necessary checks. In case of errors, the direct input technique provides a restart mechanism. However, to be able to activate the restart mechnism, direct input programs must be executed in the background only.

To maintain and start these programs, use program RBMVSHOW or the transaction BMV0.

Examples for direct input programs are:
