Patch function

Posted on by AlexMurphy

I have a PowerApp that is an Inventory system in which you can 'check out' items and then you are able to 'Check in' the notes back and works off 2 SharePoint lists.

I have written a patch function which allows the user to check in less items than originally checked out.

With(
{
SharedItemToPatch: LookUp(
Notes,
ID = varRecord3.ItemBorrowed
)
},
Patch(
Notes,
SharedItemToPatch,
{ TotalCheckedIn: Dropdown3.Selected.Value,
TotalCheckedOut: SharedItemToPatch.TotalCheckedOut - (varRecord3.TotalCheckedOut-Dropdown3.Selected.Value)
}
)
);
Patch(
'Note List log',
varRecord3,
{
Status: "Returned",
DateActualReturned: Today(),
TotalCheckedOut: (varRecord3.TotalCheckedOut-Dropdown3.Selected.Value),
TotalCheckedIn: Dropdown3.Selected.Value
}
);

The issue I am having is that when I check in the 2nd Patch function works perfectly and the Check Out column decreases but I can not replicate this on the first function. It never decreases properly.

Can anyone help as this is driving me insane

Thanks

Hi @alex_murphy ,

Firstly, I do not know your logic here, but firstly I suggest the below for the first part of each to be more specific on the record - also note the change in the drop-down.

With( { SharedItemToPatch: LookUp( Notes, ID = varRecord3.ItemBorrowed ) }, Patch( Notes, {ID: varRecord3.ItemBorrowed}, { TotalCheckedIn: Dropdown3.Selected.Value, TotalCheckedOut: SharedItemToPatch.TotalCheckedOut - (varRecord3.TotalCheckedOut - Value(Dropdown3.Selected.Value)) } ) ); Patch( 'Note List log', {ID: varRecord3.ID}, { Status: "Returned", DateActualReturned: Today(), TotalCheckedOut: (varRecord3.TotalCheckedOut - Value(Dropdown3.Selected.Value)), TotalCheckedIn: Dropdown3.Selected.Value } );

Hi @WarrenBelz

Sorry for not replying. what you should be didn't quite worked but as soon as I took off SharedItemtoPatch on the first Patch function it did.
