Duplicate SOP Master number in Dynamics GP

The credit card fulfilment add in that I wrote charges cards using sage pay API, from the GP screens or our custom SOP Fulfilment software, when the goods are despatched on a sales order.

In order for the charges to be tracked as the sales document migrates from Sales order to Invoice and subsequent fulfilments I utilise the master number of the order. However it turns out that the master number can end up getting shared by more than one document.

Master Numbers – what are they?

Master numbers can be enabled in the SOP setup screen.

SOPSetup

When ever a new document is created from a source document, they are tied together with a common master number. The stored procedure:taSopGetMasterNumber in the company database serves us with the next master number from number in this setup screen when ever a new sales document is created without getting derived from another document.

You can use master numbers in SOP Document enquiry and reporting to see all related documents as the master number ties them all together.

Our Issue

Somehow we have found that some of our sales documents have ended up sharing master numbers with unrelated documents. We have seen this with the SOP number itself too but there it is more obvious.

To find the maser numbers that are causing a problem I put together the following script that will work on SQL server 2005+. Note that we don't use back order document types so only one sales order document exists per master number according to our business logic.

WHERE ORIGTYPE=0 should help identify them if you do use back order documents, but the query will not use the indexes on the tables and thus will take a long time to execute.

-- Script to identify duplicate Master Numbers 
--  on Dynamics GP SOP Documents
With WorkHistUnion (MSTRNUMB, SOPNUMBE )as
(SELECT MSTRNUMB,SOPNUMBE  FROM SOP10100 WHERE SOPTYPE=2
UNION ALL
SELECT MSTRNUMB,SOPNUMBE FROM SOP30200 WHERE SOPTYPE=2)
SELECT  MSTRNUMB, COUNT(MSTRNUMB)from WorkHistUnionGROUP 
BY MSTRNUMBHAVING COUNT(MSTRNUMB)>1ORDER BY MSTRNUM
 

Trying this on one of our GP9 companies I got (278 row(s) affected). So we have 278 instances of sales documents sharing master numbers with unrelated sales orders. Now I have introduced a check that looks for this senario and uses the customer CUSTNMBR as a key when charging cards.

Hopefully this should stop the wrong customer getting charged for a despatch of goods – bug squished!

Why do we get this situation? Dynamics GP does not lean very much on SQL server for database integrity. This is due to the heritage of the product, rooted in DBISAM, it has never used the database to ensure integrity. SQL server is quite capable through the correct transaction handling and constraint indexes of ensuring the master numbers are not shared, but sadly it has never been written into the database.There must be some holes in the application that allows this to happen in a similar way that our telesales team sometimes manage to get the same SOP number as each other.

Edit 2011

Some more web references have shown up since 2009 when I wrote this originally, the reason behind this happening can be found in these references too:

Editing Item Description with Dynamics GP Macros

There would seem to be a problem with the Dynamic GP macros. In our GP9 installations we cannot use macros to write product descriptions over seventy two characters in length, they get truncated. My guess is that the macro engine still thinks the maximum length of descriptions is the old seventy odd characters rather than the new GP9 length of one hundred and one characters.

Anyone else found this issue? It is a real pain for us as the item managers can’t import and update hundreds of descriptions without us using integration manager or a custom VSTO excel spreadsheet.

Dynamics GP slow to login or open forms, other users ok

I notice that Ian had a similar problem that this solved too, see his post here: http://www.azurecurve.co.uk/2015/03/slow-opening-windows-in-microsoft-dynamics-gp/

Updated 2015:

GP offers a cache clear button (Remove Entries), under user preferences, I don’t think it existed/didn’t work or I didn’t know about it when this post was written, hence the drastic measures of removing the cache files. It would be wise to check the size of the cache files before and after “Removing Entries” to see if the size really does decrease. I would still advocate some audit/enforcing scheduled SQL script as mentioned later in the post to protect users from setting values for auto complete too high, especially in installations with very large numbers of items or customers/suppliers etc.


AutoComplete2

AutoComplete Setup is found from the user preference window, by clicking on AutoComplete button.

The problem report as reported:
Goods receiving, purchasing and accounts users all report some GP forms taking a very long time to open. Log in as admin or some alternative user and the problem does not occur. It was also observed that when a user’s network profile was deleted and recreated the problem went away (discovered by accident due to having to do this for other reasons and finding it solved this problem).
For information the company has over seventy four thousand items setup in inventory.

GP-Dynamics – Custom Programming a TSQL Collection

I stumbled upon this a new Dynamics GP site tonight, gp-dynamics.com. This site lists nearly one hundred useful SQL scripts to use when working with Microsoft Dynamics GP ERP system. I glanced down the list of scripts and dipped into some of them and it all looked like a good resource.

The site is orientated towards selling a technical manual on Dynamics GP, but this section is free. Of the scripts I looked at, some of them were naive, but not dangerous. Certainly enough to get out of jail free, I certainly would have relished such a resource back in 2001 when I started with GP, as it happens I have strikingly similar resource of scripts I’ve built up myself on my hard drive. A couple of examples from the site to give you the idea follow;
