Hi All,

I am having a field called "majorWork" of characters 20 size (No edt defined in base table). I am trying to increase the size of field using table extension and defining EDT as "Name" in the field properties.

I am getting error like

Error Path: IllegalEdtOnEmptyEdtField: [AxTableExtension/WorkActivityLine.Customizations/Fields/Majorwork/ExtendedDataType]:The extended data type 'Name' can't be used on the table field 'Name' because it doesn't have an extended data type specified.

any suggestions to resolve.

Note: the mentioned edt model in the field property are referenced to my custom model fyi.

Thanks in advance

As I already wrote, the author of the table must implement the field properly. Just contact the company who developed the table and remind them about MS best practices. Otherwise you can't implement the extension that you're trying to implement.

Hi Nikolaos,

Its not standard table, a custom table in a custom module . but in our environment we can able to access that custom module objects via extension/eventhandlers only.

Regarding the error "name" its an edt specified on majorwork field only. i tried with other edts like description,str60 as well. error is repeating same with replacing the edt's in the error message.

My doubt is "If a field is not provided with an edt from the beginning of table creation. Can't we change that through extension process and put desired edt as per the requirment"?

Generally all table fields should be defined using an extended data type. This "WorkActivityLine" table doesn't seem to be a standard table (although the person/company who developed it did not comply with MS naming guidelines when creating it). You should talk to the company who developed the table and ask them to add EDT to the table field. I assume it was not developed by your company, otherwise you would of course fix it yourself, and you would most likely not be extending it like this.

Also, you mention field called "majorWork", but the error message mentions field called "Name". So please check that you didn't accidentally work on a wrong field.
