quantity update from data source to another data source using dropdown in a gallery

(0) ShareShare

Posted on by Community Power Pla... Microsoft Employee

I have 2 data sources namely, try1 and Try 22 in ms lists,
I am having issues with deducting the quantity in try1 from Try22, it is like an inventory system where a user can log an item and then the quantity the user asked will be deducted from the datasource(try1), I used Try22 for logging an item while try1 are used for storing the items. It should be done by clicking a Save button to proceed. 

Here is my code for button On Select:

ForAll(
Filter(
Gallery2.AllItems,
Toggle3.Value = true
),
Patch( try1, First(Filter(try1, txtItemAdm.Text = Item )),
{
Quantity : LookUp(try1, Item = txtItemAdm.Text, Quantity) - Value(txtQtyLog.Text)
}
));

ForAll(
Filter(
Gallery2.AllItems,
Toggle3.Value = true
),
Patch(
Try22,
ThisRecord,
{
Title: lblLogID.Text,
Item: Dropdown1.SelectedText.Item,
Quantity: Value(txtQtyLog.Text),
Date: Value(DatePicker1.SelectedDate),
AssignedBy: Office365Users.MyProfileV2().displayName,
Assigned: ComboBox2.Selected.DisplayName
}
)
);


The issue in my code is that it is only updating the last record in the try1 datasource even if other item is selected from dropdown list.

    Hi @Anonymous ,

    Please try this - I am assuming here you are using SharePoint (you did not specify your data source)

    ForAll(
 Filter(
 Gallery2.AllItems,
 Toggle3.Value
 ),
 With(
 {
 wRecord:
 LookUp(
 try1, 
 Item = txtItemAdm.Text
 )
 },
 Patch( 
 try1,
 {ID:wRecord.ID},
 {Quantity : wRecord.Quantity - Value(txtQtyLog.Text)}
 )
 )
);
Patch(
 Try22,
 ForAll(
 RenameColumns( 
 Filter(
 Gallery2.AllItems,
 Toggle3.Value
 ),
 "ID",
 "ID1"
 ),
 {
 ID:ID1, 
 Title: lblLogID.Text,
 Item: Dropdown1.SelectedText.Item,
 Quantity: Value(txtQtyLog.Text),
 Date: Value(DatePicker1.SelectedDate),
 AssignedBy: Office365Users.MyProfileV2().displayName,
 Assigned: ComboBox2.Selected.DisplayName
 }
 )
)

    yes, i used sharepoint list. by the way, does {ID.WRecord.ID} and {ID: aPatch.ID} required? because the error says invalid number of arguments: received 3, expected 2.

    I did it exactly the same way you did,

    ForAll(
    Filter(
    Gallery2.AllItems,
    Toggle3.Value
    ),
    With(
    {
    wRecord:
    LookUp(
    try1,
    txtItemAdm.Text = Item
    )
    }
    Patch(
    try1,
    {ID:wRecord.ID},
    {Quantity : wRecord.Quantity - Value(txtQtyLog.Text)}
    )
    )
    );
    Patch(
    Try22,
    ForAll(
    RenameColumns(
    Filter(
    Gallery2.AllItems,
    Toggle3.Value
    ),
    "ID",
    "ID1"
    ),
    {
    ID:ID1,
    Title: lblLogID.Text,
    Item: Dropdown1.SelectedText.Item,
    Quantity: Value(txtQtyLog.Text),
    Date: Value(DatePicker1.SelectedDate),
    AssignedBy: Office365Users.MyProfileV2().displayName,
    Assigned: ComboBox2.Selected.DisplayName
    }
    )
    )

    are there some values i should change?

    @WarrenBelz  there was no errors, but it is still the same, the only record that is updating are the last record from try1, it does not update the record that is selected from dropdown list

    @Anonymous ,

    You are missing a comma at the end of the first With() statement

    @Anonymous ,

    There must be something wrong with your Lookup

    LookUp(
 try1,
 Item = txtItemAdm.Text
)

    as this is the way you are finding the correct record to update
