Can any one please assist in sorting out this issue ? My friend doesn’t want to upgrade to version 5 ( we are based in South Africa, and with the current ROA it’s just to expensive ). He’s asked me to assist him with this because when it comes to MSSQL and Computers :slight_smile: he’s clueless. I have some experience with MSSQL but can’t seem to find the source of the error.

Thank in advance

Show us the transaction.

Hi Kendash

The Error doesn’t find place with just one specific transaction in question. It find place every time you want to ADD or Edit a Transaction Document.

It happens when you navigate as follows with in Sambapos:

Manage>Inventory>Transactions>Add Transaction Document

or

Manage>Inventory>Transactions>Select any transaction and click Edit Transaction Document

In both cases the above error appears and when closed, SambaPos close completely as well.

Kind regards
And thank you for your response

It’s hard to say. It could be a bug that was fixed in v5. Maybe not. Did you try reinstalling? When did it start? Maybe a bad inventory document?

5

The system has been running for about 2-years, I’m thinking if it was a bug, why would it happen only now ? Haven’t tried reinstalling (Will give it a go) Just a question, seeing I’m new to Samba - If I reinstall, it won’t delete any of the existing SQL server instances or databases ? We can’t afford to lose any data. Can you perhaps point me in the direction of the process of reinstalling Samba? The issue started 22/02/19. I have deleted the last couple of inventory document leading up to before the Error occurred and it hasn’t proven to be a fix.

Kind regards.

No it won’t delete or change your database.

7

And the hard drive is not close to full?

8

Always run a backup first.

9

No, there are 2x 500gd HHD in the machine. And 1 is allocated for SambaPOS only.

10

:+1:t2: Will do a full SQL database backup before starting.

11

I would recommend running a backup then try deleting more documents until it works. If it starts to work you still have the backup data but at least you would know if the culprit is a bad transaction. If it doesn’t resolve you can always load the backup.

12

Will give it a try and let you know if the Error presist. Thanx for the suggestions.
