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

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.

John,
Yes! you are correct.
ClientCIN is unique for each client.

What i'm not getting is that for a new consignment, when i am entering cargo/cartons received from a specific client, that unique collection code should be assigned once while his cartons are 1 to 10 or more than 100.

Could you please give an example. Following is the sql for "CollectionVouchersubform"

SELECT CollectionVoucher.ConsignmentNo, [Consignment Number].ExportDocs, CollectionVoucher.Route, CollectionVoucher.ClientCIN, Clients.ClientName, CollectionVoucher.Destination, CollectionVoucher.DeliveryVr, CollectionVoucher.DeliveryVrDate, CollectionVoucher.CartonNo, CollectionVoucher.CartonSuffix, CollectionVoucher.TripNo, CollectionVoucher.UnitOfCarton, CollectionVoucher.ProductNameEnglish, Products.ProductNameRussian, Products.HSCode, CollectionVoucher.BrandName, CollectionVoucher.ProductQty, CollectionVoucher.UnitOfQty, CollectionVoucher.WeightOfCarton, CollectionVoucher.UnitOfGrossWeight, CollectionVoucher.[Net Weight], CollectionVoucher.UnitOfNetWeight, CollectionVoucher.UnitOfValue, CollectionVoucher.Rate, CollectionVoucher.Amount
FROM Products INNER JOIN ([Consignment Number] INNER JOIN (Clients INNER JOIN CollectionVoucher ON Clients.ClientCIN = CollectionVoucher.ClientCIN) ON [Consignment Number].ConsignmentNo = CollectionVoucher.ConsignmentNo) ON Products.ProductNameEnglish = CollectionVoucher.ProductNameEnglish;

I assume that the ClientCIN is unique to each client, so any code that uses that as the prefix will, by definition, be unique to the client. By using code to generate the next "number" in sequence, you also ensure that the code is unique within the client.

John,
Thanks for your reply.
One thing you did not mentioned, i needed for collection code is that it starts with the ClientCIN and for one consignment collection code for each Client should be unique.

Please look upon it.

Khalid

Does it matter what the alpha characters are?

You could add a field to the Clients table that lists the last alpha-number you used to generate the collection code. In BeforeUpdate of the form that creates a Collection Voucher, check to see if you're on a new record (Me.NewRecord = True), and if so, then fetch the last code from the client record, add 1, update the client record, and use the new code. When you get to 99 with the two digits, then change one of the letters and start over at 00 or 01.

Hi All,
I have been assigned a new task to generate and enter a unique collection code separately for each client, for each new consignment while entering data in form "Collection Voucher".

Logic for generating this code is that when this code is generated for clients new consignment, this code will be passed him and then he will pass this code to his authorized person at destination and that person will show or give this code to company's responsible person to deliver him the cargo.

The pattern for this code should be like starts with "ClientCIN" then two OR Three alphabets ending with two digits.

Is it necessary to generate this code in form "Collection Voucher" or some working is to be done in some other form before and then putting that code in form "Collection Voucher" ?

Help required please.
