Hi Jonfarmer4999,
You seem to have resolved an issue that I am currently having using Dynamic 365 using powerapp.
Would you please share what you did. I am finding that there is a lot of sharepoint examples but not Dynamic 365.
I have a Sample Group entity, Sample Group Detail entity (This is the entity that will get updated) and Sample Entity (The Sample entity is the combo box items.
I need to pass the sample group GUID to the powerapp from Dynamice 365 using javascript (This I can do).
The powerapp will select the existing items from the "Sample Group Detail" entity and load the data into the DefaultSelectedItems on the combo box.
If the user decided to delete or add new sample codes. I need to add/delete from the "Sample Group Detail" entity.
When the "Sample Group Detail" entity is being updated I need to store the "Sample Group" GUID on the "Sample Group Detail" entity because this is a lookup on the "Sample Group Detail" entity.
Thanks
