Support needed: critical loss of data in my collectionen/saved on device (not restorable)

[jeanshak]

A sudden stop (termination) of the app happens and no error message is been shown.
After start it new/again the local data of the app is disappeared! Also in some other files of the app.

In this way I store my data record for record in the app/local device:

Collect(LocPic;
{GEWERKNR:Text(GEWERKNR.Text);
BEM:"Freie Bemerkungen";
FOTO:upImage.Image;
CHECKED:false;
DATUM:Now();
GESENDET:"";
TOMATE:BAUVORH.Text;
BVNR:BAUVORH.Text});;
SaveData(LocPic; "LocPic"));;

Hi @jeanshak,

I replied to this issue on your another thread, a week ago:

https://powerusers.microsoft.com/t5/PowerApps-Forum/Support-needed-critical-loss-of-data-in-my-colle...

Could you please explain a bit for what kind of support that you would like to ask?

If you want to restore the lost data, then you may need to create a support ticket, which is available at the bottom of the Support page:

https://powerapps.microsoft.com/en-us/support/

Regards,

Michael

No, The data are only testdata.
The question is, WHY does the App terminate without any error. 
What can I do, to let it run more constant without sudden termination

Thanks

Jens

Start by getting rid of that semi colon after the semi colon between collect and savedata, you then have it again at the end.

this is the correct notation in Studio / installed in Germany:

; is like a comma ,
;; is like a ; 

Collect(LocPic;
{GEWERKNR:Text(GEWERKNR.Text);
BEM:"Freie Bemerkungen";
FOTO:upImage.Image;
CHECKED:false;
DATUM:Now();
GESENDET:"";
TOMATE:BAUVORH.Text;
BVNR:BAUVORH.Text});;
SaveData(LocPic; "LocPic")

the break comes not at every storage order, only sometimes ....

@jeanshak Apologies i was not aware of this, Us English ay.., so naive 

When you say termination, what do you mean? Does it throw you out of powerapps completely / back to the app selection screen?

Is it only when you press the buton or whatever control to activate this formula?

I had an issue similar a couple of months ago.  The only solution i found was to SaveAs a new app name and then use this.  I still to this day dont know what caused it.

Have you also tried removing a field at a time from your Collect function and testing.  It could be that one of the fields isnt playing nice.

[jeanshak]

yeah! 🙂
Termination means stop of the program, this purple powerapps pic arises or only the andorid screen is there. 
program finish.
It happens for example when i switch back to the app from another or while push a button, store or send. 
PLEASE SEE ALSO MY POST HERE (exact description) :

rename of the app is only a tempory solution. >> new store space.....

what field: I need a date, i need some text and this image ...... ????

[jeanshak]

What kind of fields? 
Date Fields format better as String?
Or numeric fields ?
