Hi Everyone,

I am very new to Business central.

I have a requirement where I have 2 fields

1. Field Type and 2. Value

Field type is an enum which has Int, Text, Boolean, business object as its values

and Value will hold the default values which should be related to field type values, i.e. if int is selected in Field type, the value field should accept integers.

If Text is selected then value field should accept Text data, If business object is selected then Values field should accept any business object like warehouse or customer or vendor.

P.S: This is to allow customer to create his own parameters dynamically. Even I did not understand why we are going with this approach.

Please help me out with this as I could not find any blog that is similar to this.

Is this even possible?

If yes then please help me out. If it is not possible then help me understand why as I should explain my Team lead.

Hi,

Do not worry. It is very simple. Use Data Type Variant. for your help I am sharing code here for demo.

trigger OnRun()

begin

myVariant := true;

Message('Value is: %1', myVariant);

myVariant := 1;

Message('Value is %1', myVariant);

myVariant := 'Text';

Message('Value is %1', myVariant);

end;

var

myVariant: Variant;

This code has a variable of data type variant and you can see that you can assign any value to that.

It shows you the values on running.

If this helps you do not forget to verify.

Thank you for your quick reply.

I am trying to create a field of Variant data type, but it is giving an error that Variant does not exist.

Sorry I read your question again and found that you need to use this as table field. For table field unfortunately Variant is not available. You are right. I'll think on that and will provide you some way if I find.

BC or Navision needs specific data types to be defined to a field.

it does not have any data type to be defined on the field level which can typecast itself as per the value assigned.
