API Nested loops using AL

Posted on by muthugtk 5

Hi, 

I create a Custom API using AL. I would like to work with nested loop in the api. I tried in many times, the nested loop is not working. Kindly help me to solve.

Here the code for reference.

Code:

area(content)
{
repeater(Group)
{
field(EmployeeCode; Rec."Employee No.")
{
Caption = 'Employee Code';
ApplicationArea = All;
}
part(employees; "Employees - API")
{
Multiplicity = ZeroOrOne;
Caption = 'Employees';
EntityName = 'employee';
EntitySetName = 'employees';
SubPageLink = "No." = FIELD("Employee No.");
}
field(FromDate; Rec."From Date")
{
Caption = 'From Date';
ApplicationArea = all;
}
field(ToDate; Rec."To Date")
{
Caption = 'To Date';
ApplicationArea = all;
}
field(Code; Rec."Cause of Absence Code")
{
Caption = 'Causes of Absence';
}
}

    2 things. Not sure I understand why you loop through the employees api for an employee record. Surely that’s one record. If you find the standard employee api doesn’t have enough fields just create a new one based in the original with your fields.

    For page parts it is recommended to use a guid field for the pagelink: docs.microsoft.com/.../devenv-develop-custom-api
