Hello,
I'm having an issue with Patch() creating duplicate records in my collection. My goal is to update a few fields in a record within a collection and then Patch the collection to the database to update the fields in the database. The issue I'm running into is that Patch is creating a duplicate record in the collection. I have a gallery, where a user selects a record and can delete the record. The delete is a soft delete in that a field in the record contains an IsDeleted value. Here is the collection before modification:

Here I've selected the record I wish to delete and verfied that the selected record is correct by using a label to display the PK ID of the record.

Here is the orignal collection now showing a duplicate value:

Finally, here are the various permutations of Patch I've tried to make this successfully work:
Using Lookup:
Patch(PendingEquipmentRequestsCollection, Defaults(PendingEquipmentRequestsCollection),
LookUp(PendingEquipmentRequestsCollection, ID = PendingEquipmentGallery.Selected.ID),
{IsDeleted: true, ModifiedDate: Now(), ModifiedBy:varCurrentUser.Email}
);
Using First/Filter:
Patch(PendingEquipmentRequestsCollection, Defaults(PendingEquipmentRequestsCollection),
First(Filter(PendingEquipmentRequestsCollection, ID = PendingEquipmentGallery.Selected.ID)),
{IsDeleted: true, ModifiedDate: Now(), ModifiedBy:varCurrentUser.Email}
);
Here is the validation of the selected record displayed in the label box:
First(Filter(PendingEquipmentRequestsCollection, ID = PendingEquipmentGallery.Selected.ID)).ID
If I don't include
Defaults(PendingEquipmentRequestsCollection),
Nothing happens at all, but when I include it, it duplicates. Any suggestions on what I'm doing wrong?
