Hello @yohan,

Seems like the issue is casued by your recipes therefore you should check them out carefully.

3

I would like to interplate these messages in the future, tell me how do you go about it, plus should i remove all the recipes and add them again one by one . I had tried that earlier but didn’t work though

4

I’m not 100% sure, but I would start by going through your inventory items and make sure that a warehouse is set for all items and also that the warehouse defined exists.

Deciphering crash logs is not really something we can teach anyone. It takes experience to be able to read them and pick out things that are clues. You need a very very intimate understanding of sambapos and how it works to rally understand crash logs. Even then sometimes crash logs can’t show the real picture it’s just snippets.

Thankyou all ,@ Jesse the whole point is just to have some clue a reseller, you need to sell something that you really understand.
I going through my inventory items and i have noted some recipes that are wrongly done,

7

Yes and that is why I said its really hard to teach it. But what would you like to know about crash logs in particular?

8

That tells you its something to do with inventory transaction documents.
Typically when you have an issue with inventory transaction documents it’s going to be a recipe somewhere most of the time.

From experience working with SambaPOS inventory transactions do not crash very often and there are only a handful of ways to cause a crash. Thats where the experience part comes in. Its hard to teach that. But someone that is familiar with that could look at a crash log like what you provided and immediately understand it is probably a recipe somewhere.

Eventually once you have broken sambapos enough you get where the crash logs start to make more sense. I have crashed sambapos so many times its not even funny.
