We use DBAmp to import records from another system. Everything works fine except for when creating a new record. The record does not roll-up via the summary field on it's parent. Any ideas or other information that might be helpful to help me solve this problem?

  • do you see an #Error or just wrong numbers in the summary field on the master record?

  • @rao No error. It's just the wrong numbers on the master numbers.

  • drphil - I know this is 2 years old, but what was the solution? I have the same issue in my org today.

  • I believe that the operation was running in parallel as opposed to serial and was causing record locks on the data. I believe the issue was on the DBAmp end to make that change. You might need to do a google search on how to make that change. Welcome to StackExchange and please note that your answer here is going to get deleted soon since it is not a true answer.

1 Answer 1


My understanding is upon any DML of children records of a Master-Detail relationship should kick of the asynchronous recalculation of any roll-up summary fields on the master record. Checking the Master Object, a recalculation is is still processing if there is a little purple icon next to the roll-up summary field.

If I am mistaken above, a work-around is to simulate your own roll-up summary by (1) creating a field on the Master and (2) writing a trigger on the Child that calculates the roll-up value if the field-to-be-rolled-up changes.

The work-around isn't too difficult to write, but it's not the desirable solution -- the Master-Detail should already be doing this!

My guess is that you are processing a lot of records causing a lengthy recalculation. If true, then the recalculation should occur eventually. If false, this issue has to have been documented somewhere before -- though that "Force a manual recalculation" option may be there for a reason.

Doc: https://help.salesforce.com/HTViewHelpDoc?id=fields_about_roll_up_summary_fields.htm&language=en_US

"Roll-up summary fields may take up to 30 minutes to recalculate"


Check out this doc on Bulk API and search for "Roll-up summary":


I bet your 3rd party software is using Bulk API, and maybe the ordering of how you're upserting records is causing "lock contention" with the Master records hence causing a roll-up summary failure.

  • Yea, the problem is that days go by and they don't recalc. I really didn't want to go the trigger route but I'm prepared to if I need to.

  • With a trigger, just a heads up that it might be beneficial to use an @future to recalculate the roll up so you get another execution context to work in Aug 5, 2014 at 20:00

  • Thanks! I read through that document and it looks like running in parallel as opposed to serial could cause record locks on the data. I have to wait until our SQL admin is in tomorrow to find out if he is executing the special command that makes it run in parallel instead of serial.
