Facing problem in App Engine Studio while changing the type of field from String to Reference.

[atadurwesh]

Trying to build an application through App Engine Studio, able to build it but after importing the data from spreadsheet into the issues table it takes all the field in String type then after I tried to change the field type in Reference and then save the application then It won't be taken as Reference Field.

I've attached two screenshots before the change and after the change and then after saving the Data Table and Form is remain the same.
if I go in the advance view option the I won't be able to do it from there also because sys_id is need for that.

Hi,

A reference field should be of length 32 characters. Since you converted from String, ensure it is selected.

If it still don't work after changing field length, try to delete and add again as Reference
