Resolution

To resolve this problem, use one of the following resolutions.

Resolution 1: Increase the next purchase order number or the next receipt number by one

To use this method, follow these steps:

  1. Start the Support Administrator Console, Microsoft SQL Query Analyzer, or SQL Server Management Studio. To do this, use one of the following methods depending on the program that you are using.
     

    Method 1: For SQL Server Desktop Engine If you are using SQL Server Desktop Engine (also known as MSDE 2000), start the Support Administrator Console. To do this, click Start, point to All Programs, point to Microsoft Administrator Console, and then click Support Administrator Console.
     

    Method 2: For SQL Server 2000 If you are using SQL Server 2000, start SQL Query Analyzer. To do this, click Start, point to All Programs, point to Microsoft SQL Server, and then click Query Analyzer.
     

    Method 3: For SQL Server 2005 If you are using SQL Server 2005, start SQL Server Management Studio. To do this, click Start, point to All Programs, point to Microsoft SQL Server 2005, and then click SQL Server Management Studio.
     

    Method 4: For SQL Server 2008 If you are using SQL Server 2008, start SQL Management Studio. To do this, click Start, point to All Programs, point to Microsoft SQL Server 2008, and then click SQL Server Management Studio.

  2. Run the following scripts against the company database to determine the largest purchase order number that is used.

    SELECT max (PONUMBER) as 'max po number: WORK' FROM POP10100
SELECT max (PONUMBER) as 'max po number: HIST' FROM POP30100

    Run the following scripts against the company database to determine the largest receipt number that is used.

    SELECT max (POPRCTNM) as 'max receipt number: WORK' FROM POP10300 
SELECT max (POPRCTNM) as 'max receipt number: HIST' FROM POP30300

  3. Run the following scripts against the company database to determine the next purchase order number.

    SELECT PONUMBER as 'next PO number' FROM POP40100

    Run the following scripts against the company database to determine the next receipt number.

    SELECT POPRCTNM as 'next receipt number' FROM POP40100

    Notes

    • Table POP10100 is the Purchase Order Work table.

    • Table POP30100 is the Purchase Order History table.

    • Table POP10300 is the Purchasing Receipt Work table.

    • Table POP30300 is the Purchasing Receipt History table.

    • Table POP40100 is the Purchasing Setup Table table.

  4. In the Purchase Order Processing Setup window, make sure that the next purchase order number or the next receipt number is greater than the value that you obtained in step 2.

  5. Use the appropriate method for your version of the program:

    • Microsoft Dynamics GP 10.0

      Click Microsoft Dynamics GP, point to Tools, point to Setup, point to Purchasing, and then click Purchase Order Processing.

    • Microsoft Dynamics GP 9.0 or Microsoft Great Plains 8.0

      Click Tools, point to Setup, point to Purchasing, and then click Purchase Order Processing.

Resolution 2: Add leading zeros to the next purchase order or receipt number


If the purchase order number or the receipt number does not increment, add leading zeros to the next purchase order number or to the next receipt number. To do this, follow these steps:
 

  1. Use the appropriate method for your version of the program:

    • Microsoft Dynamics GP 10.0

      On the Microsoft Dynamics GP menu, point to Tools, point to Setup, point to Purchasing, and then click Purchase Order Processing.

    • Microsoft Dynamics GP 9.0 or Microsoft Great Plains 8.0

      On the Tools menu, point to Setup, point to Purchasing, and then click Purchase Order Processing.

  2. In the Next Number column, enter leading zeros to the values in the following fields:

    • Purchase Orders

    • Receipts

  3. Click OK.

Resolution 3: Change the regional format options and language

Change the regional format options and language so that the settings match the same settings on the server. To do this, follow these steps:

  1. On the workstation, click Start, and then click Run.

  2. Type intl.cpl, and then click OK.

  3. Repeat steps 1 and 2 on the server.

  4. Verify that the settings in the "Regional and Language Options" window on the workstation match the same settings on the server.

Resolution 4: Change the Purchasing Setup Table table

Change the Purchasing Setup Table table to resolve the problem. You can either use the Enable Identity Insert option to avoid duplicate records, or you can re-create the table. To do this, use the appropriate method.

Method 1: Avoid duplicate records in the Purchasing Setup Table table (POP40100)

To avoid duplicate records in the Purchasing Setup Table table (POP40100) in the future, click the Enable Identity Insert option when you use Data Transformation Services (DTS) or the SQL Server Import and Export Wizard to transfer data from one database to another database.

Method 2: Re-create the Purchasing Setup Table table (POP40100)

Notes

  • Before you use this method, you must have all users log off Microsoft Dynamics GP and Microsoft Great Plains 8.0.

  • Before you use this method, make sure that you have a complete backup copy of the database that you can restore if a problem occurs.
