Update module FM- Exception

[Former Member]

Hi,

Can i raise exceptions in a FM that is an update module (start imm)? If i cannot raise exceptions, kindly tell me a way i can handle errors? this FM requires me to create  a Service order. and am going to call this FM in a user exit.

Kindly help.

Hello Sneha,

Updates registered via update function-modules(without the SET UPDATE TASK LOCAL addition) are executed in special work processes - UPD(Update). This is disjoint with the actual program execution & hence EXCEPTIONS are not considered for Update FMs.

If the Update terminates with an error, database rollback is issued & the update owner is notified via SAPMail.

Hi Suhas,

Thank you for the reply. but what is the difference if I use the statement SET UPDATE TASK LOCAL??

Hello Sneha,

When you use SET UPDATE TASK LOCAL before the call of the update FM, the update occurs within the same work process in which the program is being executed. Read the SAP documentation for further details.

In both the cases the execution of the Update FM is disjoint from the actual program. So i don't think this makes any difference.

The trick is to identify the causes for error and handle them before you call the FM in the update task. Only the most unusual errors should happen in there.
