We will follow the following steps in the AX development.

We will follow the following steps in the AX development. 1. Follow the naming convention: - All new objects will start with a prefix ‘INC_ModuleNameofObject’ - Adding a new field to an existing table should be prefixed with ‘INC_ModuleNameofObject’ - Created Extended Data Types for any new fields you create. - Follow the rest of the standard processes for methods, relations, indexes, delete actions. 2. Label file: - Create a new label file or use an existing for your customization. - Label file will have the 1st 3 digits of the Customer Name (Functional consultant can help         to identify the names.) 3. Please maintain a XPO for the customization, we will use it for the deployment.         Please maintain a backup and forward it to me end of the day. 4. The customization will be done on the test environment. It will be tested by the functional consultant         and then by the end user. ...

How to retrieve multiple selected records from Grid using X++

Image
How to retrieve multiple selected records from Grid using X++: In this post, we discuss how we can retrieve all selected(marked) records of a datasource or retrieve marked records form Grid. For this purpose follow the steps listed below. Create a new table named " Student " that contains two string fields i.e. Name & ID. Create a new form and add the newly created "Student" table in the datasource node. Next create a new button on the form, set its multiselect property to " Yes " . Now override the clicked method of the button and add the following code. Code snippet     int             recordsCount;     Student     studentLocal;     super();          recordsCount = student_ds.recordsMarked().lastIndex();  // Total number of marked records.     studentLocal = student_ds.getFirst(1);          while (studentLocal)     {   ...
