Posted on by Vikas Negi

Hi,

I am trying to update the Contact entity records in CDS using MS flow. I am able to retrieve 512 records by default and update the 512 records successfully. However, I want to update 50000 records using flow. First I tried to retrieve 5,000 records and update this records. When I run flow it does retrieve 5000 records but flow get fails on updating records due to time out. Could you please let me know the reason for same and how can I update 50,000 records using CDS connector in MS flow and how much time it would require to update 50,000 records?

Thanks!

Hi @Vikasdugi ,

As described by @yashag2255 , the returned content does indeed exceed the limit and cannot be executed.

You could try to filter records using other properties or use other properties to split these records into multiple parts.

Then add multiple parallel branches to update these records respectively, relying on Copy action function to quickly create multiple identical branches, like:

In addition, you could also set Apply to each to provide execution efficiency:

Hey @Vikasdugi

Can you try reducing the number of records and run the flow twice? You already have the filter query and if you are modifying that then the resultant next run will pick the remaining records.

I am guessing that the 50000 hard limit is creating this issue here for the bytes too. You could also collect these in an array and perform any further actions (using any filter queries)

Hope this Helps!

Thank you for the reply yashag2255
I have set the top count as 50000 in the list recods and 50000 as threshold of pagination in the settings as below:
When I run the flow it fails on list records and gives the below error:
Error: BadRequest. The action 'List_records' has an aggregated page results size of more than '211802208' bytes. This exceeded the maximum size '209715200' bytes allowed.

Could you please help me to understand above error and how can I resolve the same?

Thanks!

Hi @Vikasdugi

You can set the number of records to be retrieved in the Get Records/ List records action by entering 50000 in the top cound field of the action.

Currently the CDS connector supports only max of 50000 records to be retrived in flow: https://docs.microsoft.com/en-us/connectors/commondataservice/

Another way of doing this would be: create a workflow and then use XRM toolbox to bulk update those records as Flow might take a lot of time to iterate and update the 50000 records.

For the timeout issue, you can go to the settings part of the actions and change the time out to P1D (that is a day) or PT24H (24 hours) and see if it works.

Hope this Helps!
