ACCESS FEED: Re: [MS_AccessPros] Creating Unique Collection Code

John,

That is marvelous!

I simply changed the design of form and put the code on cmbClientCIN after update event.

Also amended last line as i remembered my boss told that code should start with ClientCIN+Two alpha+Two digits.

Me.CollectionCode = [ClientCIN] & [strCode]

Thank you very much John, i gained the knowledge of generating unique code.

Regards,

Khalid

That compiles and will work, but it won't do anything with CollectionCode. Needs one more line:

Private Sub ConsignmentNo_AfterUpdate()

Dim strCode As String

' Define string to generate a random letter

Dim strAlpha As String

Dim intI As Integer

strAlpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

' Set the randomizer seed

Randomize

' Generate the first letter

intI = CInt(Int((26 * Rnd())) + 1)

strCode = Mid(strAlpha, intI, 1)

' Generate the second letter

intI = CInt(Int((25 * Rnd())) + 1)

strCode = strCode & Mid(strAlpha, intI, 1)

' Generate a two-digit number between 0 and 99

intI = Int(100 * Rnd())

strCode = strCode & Format(intI, "00")

Me.CollectionCode = strCode

End Sub

John,
After running the new form "Assign clients to Consignment" and running the code you gave on the after update event of ConsignmentNo following error occurs:

Private Sub ConsignmentNo_AfterUpdate()
Dim strCode As String
' Define array to generate a random letter
Dim strAlpha = New String {"A", "B", "C", "D", "E", "F", "G", "H", _
"I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"}
Dim intI As Integer

' Set the randomizer seed
Randomize
' Generate the first letter
intI = CInt(Int((25 * Rnd()) + 1)
strCode = strAlpha(intI)
' Generate the second letter
intI = CInt(Int((25 * Rnd()) + 1)
strCode = strCode & strAlpha(intI)
' Generate a two-digit number between 0 and 99
intI = Int(100 * Rnd())
strCode = strCode & Format(intI, "00")
End Sub

Highlighted lines are showing Red in code.
In Dim strAlpha should "I" have a comma before ? like ,"I"

You need a new "Assign clients to Consignments form - and when the user picks the Consignment Number, run the code I gave you and generate a CollectionCode.

OK. made the new table ClientConsignments now what further?

Found it. You can't use Collection Voucher because there are multiple rows for each Client and Consignment. You need a new table:

ClientConsignments:
ClientCIN
ConsignmentNo
CollectionCode

Your relationships would then be:

Clients -> ClientConsignments -> CollectionVoucher
^
|
Consignment Number—+

John,
A month or so before i uploaded PTCL_be in the "Assistance Needed" folder of the group. If it is still there then you can view the relationships and design of table "CollectionVoucher". However Primery Key of table is: (as advised by you)
ConsignmentNo
ClientCIN
CartonNo
CartonSuffix

field ProductNameEnglish has Row Source:
SELECT Products.ProductNameEnglish, Products.ProductNameRussian, Products.HSCode
FROM Products
ORDER BY Products.ProductNameEnglish;

I think for our issue other fields are not necessary to mention here.

Your query implies these relationships:

Clients -> CollectionVoucher -> Consignment Number
^
|
Products —-+

What fields are in the CollectionVoucher table? That table seems to provide the many clients to one Consignment relationship, so that appears to be the place where the Collection Code belongs. However, if there can be multiple CollectionVoucher records per consignment, you have a problem because I assume the same Collection Code should be in all the records that relate to a particular Client and Consignment.

John,
First of all sorry that i was away from office and could not reply earlier.
Each consignment has multiple clients delivering their cargo of different products. Like Consignment No. 2015-A-03

ClientCIN Total Cartons
3 135
6 5
22 261
26 34
30 38
75 16
76 18
77 17

So for this Consignment No.2015-A-03 each client should have his own single Collection Code. Then on wards for next consignment each client should have his own single unique Collection Code.

I hope now i have made clear what i need.
So please guide in this situation how to manage?

Regards,
Khalid

If the Collection Voucher record is unique for each CollectionCode that you want to create, then it belongs in that table. If multiple clients can be related to a Collection Voucher record, then perhaps the code belongs in Consignment Number.

To generate a truly random value, you could use code like this:

Dim strCode As String
' Define array to generate a random letter
Dim strAlpha = New String {"A", "B", "C", "D", "E", "F", "G", "H", _
"I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"}
Dim intI As Integer

' Set the randomizer seed
Randomize
' Generate the first letter
intI = CInt(Int((25 * Rnd()) + 1)
strCode = strAlpha(intI)
' Generate the second letter
intI = CInt(Int((25 * Rnd()) + 1)
strCode = strCode & strAlpha(intI)
' Generate a two-digit number between 0 and 99
intI = Int(100 * Rnd())
strCode = strCode & Format(intI, "00")

At the end of the code, the variable strCode will contain a random value of two letters and two numbers.

John,
Good morning!
CollectionCode should itself be a new field. Not yet created, and in which table it should be ? perhaps table CollectionVoucher.

Moreover, the logic you were describing me describes that CollectionCode would be incremented by 1. This logic will be easily got by the clients. We need unique & random code. For example in consignmentNo 2015-A-03, we assign AA01 code to ClientCIN 3, then to CleintCIN 5 might have code NC39 and so on for other clients for this consignment.

Khalid
