Change field type doesn't work

[Daniel Martinek]

I need change field type Date/time to only Date type.

I decided to create new help_field and copy all dates there. And now i am wondering, why i still can't change the type, when all records doesn't contain any value there in origin field.

This approach worked on the other field and on PDI as well but with this one i have problem.

Differences between this and nonworking field are in:

 - default value: javascript:gs.nowDateTime()

 - read only

Where is the problem? What is blocking this proces? 

After changing the dataType i want to move back the dates, of course in correct format.

Hi @Daniel Martinek ,

As per my understanding you want to change field type from Date Time/ Date.

1.Please check that Date field type visibility active or not from Dictionary. Attached screenshot as ref.

Yes , i wanted to change. and i done it on other field succesfully. But the second field that with i had problem was inherited from another table and i just didnt noticed that. 
Thanks for response 😉

OK I just find the problem solution.
I couldnt change the field, because the field is inherit from another table. So i needed as first to move all records from that table field.
