Make Field in Form Mandatory

Posted on by Microsoft Employee

Hi Community,

in my PriceTable I have set the Mandatory Property for ModelId-Field to No.

In my Form Prices, when I set the Fields Vehicle Type and Vehicle Categorie (Except for "Non-Specified", I want the ModelId Field to become Mandatory.

Any Recommendations on how I could do that ?

I thought maybe I write Code in my validateWrite Method of the table, that when those two fields are set, then ModelId has to become mandatory.
But in that case, I heard it is not good on tablelevel to swtich from mandatory No to Yes .

    Thanks, I addressed the fields just like You said. And it works.

    However, it works that the Model Id field becomes mandatory.

    Also for records I had entered earlier and even for the VehicleType "Truck".... which doesn't actually make sense, since it is not part of my if-clause!!

    But how would it be possible, that the ModelId field for past records will not be marked as mandatory ?(as marked in the screenshot)

    And how can I only select that the edited or basically new record I am working on, that that ModelId shall become mandatory if the if-clause happens to be true ?

    If this Approach of mine is not good, will not be made in usual by the AX-Developers and could be handled much easier, and becomes way to complex or confusing please then let me know, so I can become better and efficient.

    Thanks in advance.

    Why don't you use datasource.fieldName like SYCFMPriceTable.SYCFMVehicleCategorie  == value.

    I am having hard time in addressing the fields or basically the formControl.

    if (SYCFMPriceTable_ds.object(fieldNum(SYCFMPriceTable, SYCFMVehicleTyp::Car)))

    it is giving me syntax error! just as for the other field, which is not an enum.

    i(SYCFMPriceTable_ds.object(fieldNum(SYCFMPriceTable, SYCFMVehicleCategorie == "Non-Specified")))

    How do I address those fields in my form correct ?

    You may solve this issue in two steps

    1) implement condition on active() method of form data-source

    If(Vehicle Type and Vehicle Categories)


     //Set any field mandatory




    //set non-mandatory


    2) implement same logic on table ValidatWrite()

    Step#2 will make sure that data entry from table level gets correct.

    Please note that if you are using any data entity for DIXF, you would need to see how you want to handle the situation with use of DIXF
