Function modules in Update task

From F1 Help...

<i>

This statement registers the update function module specified in update_function. update_function must be a character-type field, which during execution of the statement contains the name of an update function module in uppercase letters.

<b>An update function module is a function module, for which in the Function Builder the property update module is marked. The registration of an update function module is an essential part of the update task.</b>

The function module is not executed immediately, but is scheduled for execution in a special work process (update work process). For this purpose, the name of the function module including the passed actual parameters is stored as a log record in the database table VBLOG. If the statement is executed during the update task, the addition IN UPDATE TASK is ignored.

Hi Bhavani ,

1.If a function module contains in attributes 'Update mode ' and run( without 'update task - keyword).

<b>It will behave as a normal FM . The update mode in attribute has no effect .</b>

2.call function ' fun2' in update task.

In this case, do we need to set the attributes must be 'Update task'?

<b>Yes the attribute 'Update Task' must be set . Otherwise you will get a run time error CALL_FUNCTION_NO_VB. In this way the function will be executed when your program hits a commit work statement and will be executed in a sepaarte task ( not in the dialog task in which your program was running ) called update task.</b>

Cheers.
