SAP Note 19824 - Batch input with CALL TRANSACTION USING and CPIC

Symptom:

The CPI-C connection terminates during batch input with CALL TRANSACTION ... USING.

Cause and prerequisites

Batch input with CALL TRANSACTION ... USING has an incorrect screen sequence.

Solution
The program occurs when a warning appears on the screen during a transaction. In this case, after , the same screen is processed again online. In batch input, the screen in question must then exist TWICE in the session. Otherwise, the warning will be followed by the next screen, which is not correct in this situation, and the transaction terminates. As a result, any open CPI-C connections are terminated, and the subsequent send and receive calls end with an error because the connection is no longer up. The SysLog contains an entry with the text ">CPIC function: CMSEND(A)" (for example) and message identifier "R64" in the technical details.
