Customization Example

The following example illustrates a way to add custom functionality to a guidelines and restrictions check. Customer one wants to set up custom guideline checks for their customer Finger Foods Bodega, used as an example, who wants a specific vendor to be the only supplier of certain items. Specifically, Finger Foods Bodega would like all frozen pizzas that they resell to have the cheese sourced from the example vendor Cheese Are Us. To accomplish this, Customer one will use the postItemGRCheck script hook and use an extension table.

Create a generic standard guideline object called MUSTUSEVENDOR.
Create an Extension Table in the Extension Table Definition form.
1. Specify Company as the supported symbol for MUSTUSEVENDOR.
2. Add rows for the extension table definition in the Columns tab.
Open the company object for your customer. Add a row in the Extension Tables tab and specify the Vendor and Standard Guideline that you created in step 1.

Write code for the script hook in the FGUIDELINE symbol.

The hook script contains the following code:

Option Strict Off
Imports System
Imports System.Data
Imports System.Collections.Generic
Imports System.Diagnostics


Class HookScript
 Inherits FcProcFuncSetEventHook

Function postGRItemCheck () As Long
	Dim retVal As Long = 1
	Try
		If _FORMULAGLINGR Is Nothing OrElse _FORMULAGLCUSTOMERS Is Nothing Then
			Return 1
		End If
		Dim Items() As String = _FORMULAGLINGR
		Dim Customers() As String = _FORMULAGLCUSTOMERS

		For Each customer As String In Customers
			Dim ds As DataSet = ObjectDataSet("COMPANY", customer, "HEADER;MATRIX")
			Dim MustUseList As New List(Of VendorMustUse)
			MustUseList.Clear()
			For Each customTableRow As DataRow In ds.Tables("FSCOMPANYMATRIX_0").Select()
				Dim mustUse As New VendorMustUse
				'In FSCOMPANYMATRIX_0 extension table for customer FIELD2=ITEM, 
				'In FIELD4=VENDOR, FIELD6=STD GUIDELINE TEXT
				mustUse.item = customTableRow("FIELD2")
				mustUse.description = customTableRow("FIELD3")
				mustUse.vendor = customTableRow("FIELD4")
				mustUse.stdGR = customTableRow("FIELD6")
				MustUseList.Add(mustUse)
			Next

			'If there is an item for the formula that matches an item in the "Must Use" 
			'extension table, create a new row in the result table.
			For Each item As String In Items
				For Each must As VendorMustUse In MustUseList
					If item = must.item Then
						Dim grLineId As Integer = 1
						Dim tempDs As DataSet = ObjectDataSet("", "", "RESULT")
						Dim rows() As DataRow = tempDs.Tables("FSFGUIDELINERESULT").Select("OBJCODE='" & item & "'")
						If rows.Length > 0 Then
							grLineId = rows.Length + 1
						End If
						Dim newResultRow As DataRow = GetNewRow("", "", "RESULT")
						newResultRow("OBJTYPE") = "0"
						newResultRow("OBJCODE") = must.item
						newResultRow("OBJDESCRIP") = must.description
						newResultRow("STDSTMTTXT") = must.stdGR.Replace("(&Vendor)", must.vendor)
						newResultRow("FORMULA") = _OBJECTKEY
						newResultRow("GR_LINE_ID") = grLineId
						RowUpdate("", "", "RESULT", newResultRow)
						CommitNewRow("", "", "RESULT", newResultRow)
					End If
				Next
			Next
		Next

	Catch ex As Exception
		retVal = -1
		MessageList("Exception:" & ex.ToString)
	End Try

	Return retVal
End Function

Class VendorMustUse
	Public item As String
	Public description As String
	Public vendor As String
	Public stdGR As String
	Public Sub New()
	End Sub
End Class

Run a guideline check on a formula. Specify the company in step 4 in the Customer field and click Check Guidelines. The custom guideline is added to the Standard Guideline field.
If the customer is referenced on the formula, it will already be in the Customer field.

This example is to show one scenario, but given the flexibility of scripting, any number of scenarios for custom guideline checks are possible.
