Upgrading Great Plains Dexterity Customization – switching to new technologies: SQL, Crystal, eConne

1. Replace Dexterity cursor with SQL Stored Procedure

Dexterity was designed as multiplatform technology (primarily Btrieve, Ctree, SQL Server, potentially Oracle). Dexterity data retrieving mechanism is based on Range start, Range End, Get First and Get Next clauses. It is in fact similar, however a little bit slower to cursors in Transact SQL. Long ranges in Dexterity are good candidates for replacement by SQL stored procedures with update clause.

For example, consider to replace following Dexterity code:

Range clear SOP_HDR_WORK.

Clear ‘SOP Type’ of table SOP_HDR_WORK.

Clear ‘SOP Number’ of table SOP_HDR_WORK.

Range start table SOP_HDR_WORK.

Get first table SOP_HDR_WORK.

While errEOF do

If ‘Salesperson ID’ of table SOP_HDR_WORK = “ERIC” then

Edit table SOP_HDR_WORK.

Set ‘Salesperson ID’ of table SOP_HDR_WORK to “BILL”.

Save table SOP_HDR_WORK.

End if.

Get next table SOP_HDR_WORK.

End while.

With the following SQL code

Update SOP10100 set SLPRSNID=”BILL” where SLPRSNID=”ERIC”

Bringing new data into a table in Dexterity is based on change/edit table clauses, in SQL they are equivalent (by performance) to inserting one record at the time.

When having long cycle of change/edit table in Dexterity, consider replacement by SQL stored procedure with Insert Into clause.

2. Use Crystal Reports, call them from via VBA in Modified form

The easy way to call Crystal Report from your VBA code from your modified form:

Const RPT = “D:\Clients\TheClient\Invoice Status.rpt”

Public crwApplication As CRPEAuto.Application

Public crwReport As CRPEAuto.Report

Private Sub Print_BeforeUserChanged(KeepFocus As Boolean, CancelLogic As Boolean)

If SalesTransactionInquiryZoo.Type = “Invoice” Then

If crwApplication Is Nothing Then

Set crwApplication = CreateObject(“Crystal.CRPE.Application”)

End If

Set crwReport = crwApplication.OpenReport(RPT)

crwReport.ParameterFields(1).SetCurrentValue (DocumentNo)

crwReport.Preview

End If

3. Use Direct .Net Web Publishing from Great Plains Database

The easiest and safest way is to use eConnect – SDK with VB samples, created for eCommerce programmers and web designers to call the functionality in Microsoft Great Plains. If your company can not afford eConnect – create your own set of stored procedures to address Great Plains database and go ahead with Visual Studio.Net to do the web publishing.
