Clearing out a multi-select option field in Dynamics 365 from Flow

[ishraqiyun77]

I have a multi-select option field in Dynamics 365 that needs to be cleared out after a Flow runs. It is really just a temporary field to create other related records.

I've tried adding the null function to the field on the entity:

This just makes the Flow fail with "Bad Request" and talks about how that doesn't match any of the option set values.

I've tried adding the false function to the field on the entity:

This just makes the Flow fail with "Bad Gateway".

Any other suggestions?

Hi @ishraqiyun77 ,

I have made a test on my side and you could refer to workaround below to create the flow:

Note: Create an item with null value in the Multiple column, and then update the item (that you want to update) with the null value Multiple column dynamic content, an you could delete the item later.

I have the same problem. The field doesn't accept null values.
