HI,

Need some information.

My Requirement is, there is one concept, GOS. By using this we can upload the images to the server.

And then we can display also.

Now i am developing one Custom screen, in this i need the GOS functionality, For this, I has to create one Zcustom Object.

I was Created but while Releasing it is showing that Object Contains 8 Errors.

Please have a look on below attached images.

Need valuable suggestions.
