Choose a transaction and write a Batch Input program with 'Call Transaction'. Do not use the Messagetab feature of 'Call Transaction'. In this case the last error message will be at the SY-MSG* system fields. Recreate the complete error message from table T100! (This example is also used by the demonstration of SY-MSG* system fields)
Solution:
REPORT ZSYSTEM LINE-SIZE 255.
TABLES: T100.
* Batch-input data
DATA: BEGIN OF G_BDCDATA OCCURS 100.
INCLUDE STRUCTURE BDCDATA.
DATA: END OF G_BDCDATA.
DATA: G_MESSAGE(200).
PERFORM FILL_BDCDATA.
CALL TRANSACTION 'FI01' USING G_BDCDATA MODE 'N'.
* of course it is nicer with a message itab, but this example
* should also demostrate the use of system variables.
SELECT SINGLE * FROM T100 WHERE
SPRSL = 'E'
AND ARBGB = SY-MSGID
AND MSGNR = SY-MSGNO.
G_MESSAGE = T100-TEXT.
