Powerapps very slow to patch to sharepoint list

Hi All, 


I'm building a timesheet app for my company and facing a delay/latency issue with submitting to sharepoint list. here's how my app is built:

1. I'm pulling a full list of workers names, IDs, etc from a sharepoint list to a collection 

2. using a gallery to  update the collection with regular hours/overtime and presence status for each worker. 

3. a save button with patch command to patch the collection to a sharepoint list. 


the problem I'm facing is the app is taking 2-5 min to submit the collection (about 50 lines), and if the user exit the app before it finishes uploading the data, the process will not complete... Please help. thank you

Re: Powerapps very slow to patch to sharepoint list

Hi @mohaimen88 ,

Could you please share more details about the formula you used in your app to patch collection to your SP List?


Actually, there are many reasons that an app can be slow to load, slow to respond, and slow to write to data sources. Please check the performace suggestions in the following blog:


If you want to patch a collection back to your SP List, the standard formula as below:

                LookUp('YourSPList', ID = Collection1[@ID]),
                   Column1: Collection1[@Column1],
                   Column2: Collection1[@Column2],
                   Column3: Collection1[@Column3],


In addition, please mak sure the Network on your side is in a good condition and the available RAM is enough on your PC. The Network state and available RAM would also affect the data process in your app.


Please also check if the following performance tips for canvas app would help in your scenario:

Thank you Kris, I tried the threads you sent with no luck. 


here's the formula I'm using: 

ForAll(ColLabor, Patch(TS_LIST, Defaults(TS_LIST), 
    TS_LABORNAME: L_LaborName,
    TS_LABORNUM: L_LaborNumber,
    TS_PROF: L_Prof,
    TS_PROJECT: L_Project,
    TS_REGHOURS: L_Hours,
    TS_REMARKS: L_Remarks,
    TS_DATE: F_Date.SelectedDate,
    TS_CreatedBy: DD_CreatedBy.Selected.Title,
    TS_ABSENT: L_Absent
