Adding values to an Enum EDT

(0) ShareShare
ReportReport
Posted on by 275

I have a base enum that I want to add values to and to change the default value of. I don't know where else in AX this base enum is being used so it is my understanding that it would be better to make an EDT based on that base enum and then make changes to the EDT. The problem I'm having is after making the enum EDT and setting the enum type I'm not sure if I can do what I want to or not. If I add an array element I'm still not seeing anything other than the base enum values in my combobox that is displaying the values of the EDT.

Is this possible or do I misunderstand EDTs?

    Hi Thills,

    The array element of an EDT is for creating multiple instances of one field. E.g. the sorting fields on a project.

    For a base enum you have to add a new option directly on the base enum.

    You have to check first if you don't break any logic of AX. E.g. create a new status and use this one might eequire aditional checks in standard posting logic.

    It is also recommended to have a gap in the numeric value for future Microsoft additions.

    On a table method called initValue() you can set the new default value for this field.
