lr.start_sub_transaction

Starts a sub-transaction specified by its parent's name.

C#

void   lr.start_sub_transaction( String  sub_transaction, String  parent_transaction );

VB.NET

Sub lr.start_sub_transaction( ByVal sub_transaction As String, ByVal parent_transaction As String )
Example: lr.start_sub_transactionTransaction Functions

Arguments

NameComments
sub_transactionThe name of the sub-transaction
parent_transactionThe name of the parent transaction in which the sub-transaction is nested.

The lr.start_sub_transaction function marks the beginning of a sub-transaction. To mark the end of the sub-transaction, use lr.end_sub_transaction. You insert these functions immediately before and after the sub-transaction actions.

Sub-transactions are used for isolating parts of a business process. For example, a sub-transaction "electrical_purchases" may be nested within the larger transaction "purchases." The transaction "purchases" is the parent transaction and "electrical_purchases" the sub-transaction.

Multiple sub-transactions can be nested within a parent transaction. A sub-transaction may also be a parent to a smaller sub–transaction.

The duration of a transaction or sub-transaction is the sum of the durations of all steps between its start and end, including the steps that are included in sub-transactions.

Each lr.start_sub_transaction statement must be matched with an lr.end_sub_transaction statement within the script or it will be interpreted as an illegal command.

Note: For information on allowed characters and maximum length for transaction names, see the transaction guidelines in the VuGen Help Center.
