Not one standard function module, but many can be called in an update task. In the function module, you specify that you can call it in update task, then when calling the function module, you add the extension IN UPDATE TASK.

CALL FUNCTION
Variant 3
CALL FUNCTION func IN UPDATE TASK.
Additions:
1. ... EXPORTING p1 = f1 ... pn = fn
2. ... TABLES p1 = itab1 ... pn = itabn
Effect
Flags the function module func for execution in the update task. It is not executed at once, but the data passed with EXPORTING or TABLES is placed in a database table and a subsequent COMMIT WORK then causes the function module to be executed by the update task. Update function modules must be flagged as such in the Function Builder
The return value is not set.
Addition 1
... EXPORTING p1 = f1 ... pn = fn
Effect
Values of fields and field strings specified under EXPORTING are passed from the calling program to the function module. In the function module, the formal parameters are defined as import parameters. In the interface definition, default values must be assigned to all import parameters of the update function module.
Addition 2
... TABLES p1 = itab1 ... pn = itabn
Effect
TABLES passes references to internal tables. All table parameters of the function module must have values.
Note
With update function modules, both import parameters and exceptions are ignored when the call is made.

First Create your function module in SE80.
In the attributes tab, under processing type, choose Update Module, Start Immeditatly. Define your import parameters, enter the source code, All validations should have been done prior to the call to this function module, so all you need in the source, is the updating of the database, INSERT, MODIFY, UPDATE, whatever.
When you call you function module, use IN UPDATE TASK, after the call, COMMIT WORK. The commit work will trigger the db update.
