Hi ,

We dont use Update FM to update database table. We can use lock objects on the table and modify the table values in case of custom objects or we use BAPI to update standard tables. However sometimes, we may need to change data of standard documents which we may need to modify. In such cases, we use update FM where it gets triggered after database commits and we use the document number generated to modify subsequent documents' data.

Thats more a how than a why Question. And the Why is very hard to hard to explain without going back 1980. A pros and cons discussion on the Update task would be useful. I personally think there are more negatives than positives for using the update task.

Sorry but pretty much every sentence in this comment is inaccurate in general.
