C Sharp Program to get 1000 records
in Microsoft Dynamics GP 2010 using Web Services

Handling 1000+ records in MS Dynamics Great Plains
When a call is made to GetCustomerList method, only the first 1000 records are received. . This is not possible in the GP 10 because the number of records for the GetCustomerList is fixed to 1000 in the Dynamics GP Web Service. To receive the complete list of the customers from the RM00101 table, use the following code.
To call more than 1000 records call the GetCustomerList in a loop. Use the last customer number from the first 1000 records and get the next 1000 records from that customer number.
C# Program Code
CompanyKey companyKey;
Context context;
// Create an instance of the web service
GPWebReference.DynamicsGP wsDynamicsGP = new DynamicsGP();
//Web Service credentials
wsDynamicsGP.Credentials = new System.Net.NetworkCredential(“DomainUserName”, “DomainPassword”,”DomainName”);
// Create a context with which to call the web service
context = new Context();
// Specify which company to use (sample company)
companyKey = new CompanyKey();
companyKey.Id = -1;
// Set up the context
context.OrganizationKey = (OrganizationKey)companyKey;
context.CultureName = “en-US”;
// Create variables to store the last customer ID and Name returned by the GetCustomerList method.
string strLastCustomerNumber = “”;
string strLastCustomerName = “”;
// When results are returned by method call, this variable will be set to 1
int intResultsExist = 0;
// Create a CustomerCriteria object
CustomerCriteria customerCriteria = new CustomerCriteria();
// Create a LikeRestrictionOfstring for Customer Name that starts with a C
LikeRestrictionOfString customerNameCriteria = new LikeRestrictionOfString();
customerNameCriteria.Like = “%”;
// Create a LikeRestriction for Customer ID used later
LikeRestrictionOfString customerIDCriteria = new LikeRestrictionOfString();
// Create CustomerSummary object
CustomerSummary[] customerSummaryList;
try
{
// Set Customer Name Criteria for first GetCustomerList call
customerCriteria.Name = customerNameCriteria;
// Retrieve the list of customer summaries
customerSummaryList = wsDynamicsGP.GetCustomerList(customerCriteria, context);

// Add to the Total Customer Counter
totalCustomerCount = totalCustomerCount + intCustomerCount;
// Evaluate whether iCustomerCount is larger than or equal to 1000. If it is, set the iResultsExist and call the GetCustomerList method again.
