    Hi Krishna,

    Could please confirm that attribute3 is not equal to "Null" ? Otherwise you need to check it explicitly before assignment.

    Try to wrap the C# call into CLRInterop::getAnyTypeForObject(), then that return value could be assigned to an AX primitive/type.

    @ievgen:

    ATTRIBUTE1 ATTRIBUTE2              ATTRIBUTE3 ATTRIBUTE4                 PAYROLL_ID

    NULL             2017/07/29 00:00:00 NULL          PAYROLL_29-JUL-2017 162

    @Vilmos:

    could you please suggest or share any link how to do this with CLRInterop::getAnyTypeForObject()

    Thanks

    Wrap it around your C# call, then you could assign it to your local AX variable in X++. Just like in the documentation for the function.

    But what actually stops you from checking that its not null before doing assignment ?

    Hi ievgen,

    how to check whether it is  null in AX.

    if (!extRow.get_PAYROLLINTERFACEID())// is it correct.

    You already have the solution above, why do you want to complicate it by checking for null value for the C# return type?

    Converting it to AX anytype using the CLRInterop class will give you an AX null value for value assignment if it is empty, or the actual value if it has any provided.

    if (ClrInterop::isNull(myObject))

    How to assign array buffer from C# to AX table buffer.

    You could find in very first reply (attachment)

    1. Here I am assigning Array field values to variables

    2. Assigning variable values to table fields. (table.Field1 = "variable";

    Is there is a  way to assign directly array buffer to AX table buffer?

    (like AXTable = ArrayBuffer).

Under review
