Can you go to Service Center and check the error detail, with only the image is difficult to help

If you clicked on view error report it would open a notepad stating which attribute had the problem, It is in the Phone attribute, check the attribute datatype it is phone number so it refuses text value which you typed CSC.

If that doesn't work can you please share more info, can you click any of these. That way you can share with us the Service Center log. 

You need to check data type, limit type, Max length, ... anything related to data validation.

You also check field by field, for example: phone number, password, ...

And the last if you can not create data althought all data is correct then your ide is blocking.

Could you share the module (.oml) or a sample application that reproduces the issue?

The error message shown in the screenshot is quite generic, and without the module or the detailed error report it's difficult to determine the exact root cause. If you share the module, community members can import it into their Personal Environment and verify whether the issue is related to the entity definition, database synchronization, data type configuration, or an environment-specific problem.

Hi Nivetha,

1. Whenever you have an error trying to do something, please, look at the error. If you can't solve the issue after looking at the error, when asking a question, share the error.

2. All summarize some of the possible reasons for you to not being able to add records from inside Studio.

a) You just added the entity and didn't yet published the module. For the editor to work, the entity must be created.

b) You had published the entity, but since the last publish, you changed the entity and didn't published it yet. You may have deleted mandatory References (foreign keys). You don't see the attribute anymore, but it is still on the database table and the database is expecting something, raising an exception when you try to add records without a value.

c) Wrong data types could cause problems, but I am not seeing anything in your screenshots that tells me it is a data type problem.

d) Text exceeding the attribute's length. This can create an exception as databases don't like to silently truncate information (it becomes a hidden error), but again, does not seem the case here.

While there are other situations (much less likely to happen), I would say the most probably reason for your problem is that you created the entity, didn't published the module, and tried to add data.

Considering the date of your post, if that's the reason, I will assume you already solved the issue by now.

Let us now, please :)

Cheers.
