LEAVE TO TRANSACTION
Other versions: 7.31 | 7.40 | 7.54
Syntax
LEAVE TO { {TRANSACTION ta} | {CURRENT TRANSACTION} }
[AND SKIP FIRST SCREEN].
Addition
Effect
The statement LEAVE TO TRANSACTION
calls either the
transaction whose transaction
code is contained in data object ta
, or the current transaction. The data object ta
must contain the transaction code in uppercase.
When CURRENT TRANSACTION
is specified, the current transaction is called
using the transaction code that was used to call the transaction using CALL TRANSACTION
or LEAVE TO TRANSACTION
. This transaction code is contained in the system field sy-tcode
except for
parameter transactions or
variant transactions.
When using parameter actions or variant transactions, their transaction code is used for the call and sy-tcode
contains the name of the implicitly called
dialog transaction.
When using LEAVE TO TRANSACTION
, the current
call sequence is exited
completely. Upon completion of the called transaction, the runtime environment returns to the position where the first program in the call sequence was called. The current
SAP LUW is thereby ended.
When the transaction is called, the ABAP program associated with the transaction code is loaded in a new internal session. All previous internal sessions are deleted from the stack. At the same time, the
ABAP memory is deleted,
which means that EXPORT FROM
MEMORY or IMPORT TO MEMORY
do not transfer data when using LEAVE TO TRANSACTION
.
The steps of the called dialog transaction or OO transaction are the same as with CALL TRANSACTION. When the called transaction is exited, the runtime environment returns to the position where the first program in the current call sequence was called.
If the transaction specified in ta
is not found, or if ta
is initial or blank, the stack of the current call sequence is deleted and the runtime environment returns
directly to the position where the first program in the current call sequence was called. If ta
is not initial, an appropriate message appears in the status bar.
The LEAVE TO TRANSACTION
statement always terminates the current call sequence, regardless of whether or not a new transaction can be called.
Contrary to the statement
CALL TRANSACTION, the authorization of the current user for executing the called transaction is always automatically checked by the
authorization object S_TCODE when using the statement LEAVE TO TRANSACTION
.
Notes
-
You can use
CURRENT TRANSACTION
in the call to execute a current parameter transaction or variant transaction with the corresponding parameters or the transaction variant. Alternatively, the method GET_CURRENT_TRANSACTION of the class CL_DYNPRO can be used to obtain the transaction code of the current transaction. This method returns the transaction code during a parameter transaction or variant transaction instead of the transaction code of the implicitly called dialog transaction. -
If procedures are still registered at
LEAVE TO TRANSACTION
in the current SAP LUW, the SAP LUW is ended and the procedures are not called or rolled back. Registered update function modules remain in the database, but can no longer be executed. In a case like this, therefore, it is advisable to execute the statement COMMIT WORK orROLLBACK WORK
explicitly before the program call.
Addition
... AND SKIP FIRST SCREEN
Effect
The addition AND SKIP FIRST SCREEN
has the same meaning as with CALL TRANSACTION
.
