Transactions for Workflow Start
Use
The workflow system can generate a form transaction for workflows that have a structure as an import parameter. Data can be entered in the fields of the structure with the form transaction and the workflow is then started.
You can edit this transaction at a later date using the ABAP Workbench, for example to change the names of input fields or adapt the layout.
If you select a workflow in manual workflow start for which a form transaction is defined, this form transaction is executed. The workflow system responds in the same way if a
start transaction had been created for the workflow in an earlier release. For more information, see Starting Workflows Manually.Features
The workflow system generates a form transaction for a workflow with a structure as an import parameter to start this workflow. The input fields are derived from the fields of the import structure of the workflow container.
The workflow system generates the name of the transaction automatically from the ID of the workflow. The workflow system also generates the name of the function group automatically if you do not specify anything on the Function group tab page.
Activities
You generate a form transaction in the basic data of the workflow in the Workflow Builder. To do this, select 
on the Start forms tab page in the version-dependent basic data. You can also process existing start forms from here. For more information, see
If a start transaction was created for the workflow in an earlier release, you can also edit this in the version dependent basic data on the Start form tab page.
You can use the Screen Painter functions to revise the transaction generated. For more information, see
Screen Painter.
If you want to change the user interface status of the transaction generated, you must define a separate user interface status. You can use the user interface status
