Posted on by Syed Safwan

When it enters the loop it should check if a job number already exists or not if exists it should increment like 001 to 002

for example Sell-to Customer No = 1000
job number will be1000-001
if 1000-001 exist the it should increment to 1000-002

code:

trigger OnAfterValidate()

var

GetNo: Text;

begin

GetNo := '';

Rec.get(rec./No./);

if Rec.FindSet() then

repeat

GetNo := Rec./Sell-to Customer No./ + '-' + IncStr('001');

Rec./No./ := GetNo;

Rec.Rename(GetNo);

until Rec.Next() = 0;

end;

Hi,

I am not sure what you are trying to do but

To put it simply once you get new number generated - Just verify using If not .GET() then assign value otherwise keep repeating.

It sounds like you can do it with the standard No. Series feature. For example, you can define a No. Series for each customer. When creating a job, the system can automatically pick up the number.

Hope this helps.

Thanks.

Hi there!

As Yhun Zhu has commented, if you are trying to increment No. Series for documents you need to use the standard feature.

However for the sake of resolution, basing on your code, here is my suggestion. The following code checks if a job number already exists for a customer and increments the suffix accordingly:

A more 'elegant' solution would be in any case to generate those auto incremental job numbers utilizing the existing Business Central No. Series functionality (No. Series Management Codeunit), which is realiable and well-integrated.

Hope it helps!

BR,

JM

I would argue the case you do not need your Customer Number included in your Project/Job No.

On the Project you select the Customer of that Project. From the Customer you can look up their Projects. From the Project list you can Search (or Filter) for your Customer No., and it will show all Projects for that Customer.

There is really no need to include the Customer No. in the Project No. This could be an example of developing something from the old system that didn't have the features/capabilities Business Central does for linking Customers and Projects.
