Modifications involving number sequences
Below is a short description of how to implement the number sequence framework for a new module in Axapta. The description is presented step-by-step. Some of the steps might be irrelevant if they have been carried out previously for other purposes in your new Axapta module.
The new module is referred to as MyModule in the description.
1. Create a parameter table for the new module: MyModuleParameters. This table must follow the standard Axapta design for parameter tables. This means that the table must, at a minimum, contain a Key-field, and the standard method: Find. Furthermore, some standard methods must be overloaded (delete and update). These can be copied from one of the other parameter tables.
2. Add your module to the NumberSeqModule in Base Enums.
Note
The module name is used to detect the active number sequence references in your Axapta installation.
3. Implement static methods.
o MyModuleParameters::numberSeqModule()
Reference your module here:
o MyModuleParameters::numberSeqReference()
Copy these from one of the other parameter tables, and change the names
4. Add line in method.
Add MyModuleParameters::Find() in method Company.selectParameters()
5. Create a form to display the new parameter table.
It's important that the functionality of number sequence references is copied exactly from one of the other parameter forms (e.g., copy methods, query, properties, etc.) Remember to correct names of the called methods
6. Create new class.
NumberSeqReference_MyModule and let this class extend class: NumberSeqReference
7. Add line in method.
NumberSeqReference::Construct()
Copy one of the existing lines and change the class name.
8. Add line in method.
NumberSeqReference.loadAll()
Copy one of the existing lines, and change the name of parameter table.
Your framework is now established. When you run your new parameter form, you should not get any errors. On the Numbersequence tab page, you should get the message: 'No setup required'.
To make number sequence references for your new module, you must:
* Override the NumberSeqReference.loadModule() method.
* Create a new method: NumberSeqReference_MyModule.loadModule().
In this new method, specify each reference needed in your new module.
Please refer to the documentation on NumberSeqReference.loadModule() method for details on how to create a reference.
After creating your references, the system will automatically detect them when opening the new parameter form. This is now visible in the grid on the Numbersequence tab page.
How to refer to your new references
For each reference specified in NumberSeqReference_MyModule.loadModule(), you must create a static method on your parameter table. Assuming you have specified a reference for the data type MyDataType, you need to create the method MyModuleParameters::numRefMyDataType().
Copy a numRef method from one of the other parameter tables, and change the names of the method to numRefMyDataType, and the referred datatype to MyDataType.
You are now ready to use the reference from the X++ code, for example:
MyNewId = NumberSeq::newGetNum(MyModuleParameters::numRefMyDataType()).num();

Subject: [development-axapta] number sequence
Hi all,
Perhaps this is a silly question, but is there a way to check if a
number sequence exist from x++ code?
I thought I would get full acces to them by using a variable of the
type NumberSeq. But I can't see how.
Logically the next question would be: if this is possible, would i be
able to create a new number sequence with X++ if the number sequence
did not exist.
Any thoughts on this are welcome.
