Hi All have Patch Logic on a command button

Patch(' XX Invoice Headers',Self.Selected.Item,{Transfer:true}) 
 
it appears to work for the first invoice I select in a session but if I try and do more than one it does not. It doesn't set the column value. Anyone ever see this before? Thx

Hi @ctedesco3307,

Why it happens:
Self.Selected.Item in command bars can become stale after the first execution. The Patch then runs but does not update the record.

How to fix:
Re‑resolve the record using LookUp, or use ForAll(Self.Selected.AllItems) for grids. Do not rely on Self.Selected.Item alone.

Example fix:

Patch(
'XX Invoice Headers',
LookUp(
'XX Invoice Headers',
InvoiceHeaderID = Self.Selected.Item.InvoiceHeaderID
),
{ Transfer: true }
)

This is a known behavior and already discussed in the Power Platform Community.

Explanation:
The Self.Selected.Item property in Command Bars often holds a cached version of the record from the moment the screen or control was initialized. If a user modifies a record and then immediately clicks a command bar button, Self.Selected.Item may still reflect the pre-modified state. This leads to a "silent failure" where the Patch executes but essentially overwrites the new data with the old cached data.

By using a LookUp within the Patch function, you force Power Apps to fetch the most recent version of the record from the data source using its Primary ID. This bypasses the local cache.

Using Self.Selected.AllItems is often more reliable because it references the collection of selected items currently held in the control’s buffer, which tends to be more reactive than the single Item property.

In a command bar (modern commanding) in Power Apps:

Self.Selected.Item is not refreshed after the first Patch

So:

First click → works

Next clicks → use outdated record reference

Always re-fetch the record using its primary key and refresh the data source.

Try below:

Patch( 'XX Invoice Headers', LookUp( 'XX Invoice Headers', ID = Self.Selected.Item.ID ), { Transfer: true } ); Refresh('XX Invoice Headers');

The fix is:

Do not use Self.Selected.Item directly

Use LookUp() with the record ID

Add Refresh() after Patch

Hi @ctedesco3307,

Agree with the answers above. Self.Selected.Item holds a cached reference after the first Patch which causes silent failures on subsequent clicks.

The fix is to re-fetch the record via LookUp and add Refresh after:

Patch(
'XX Invoice Headers',
LookUp('XX Invoice Headers', InvoiceHeaderID = Self.Selected.Item.InvoiceHeaderID),
{ Transfer: true }
);
Refresh('XX Invoice Headers')

Best regards,

Valantis
