Error message - "Invalid Dimension" while using Date field

[AMS123]

Dear All,

While making a line chart, I am getting an error message of "Invalid dimension" while putting Date field in it. I tried with other data from different excel sheets and it works quite well and therefore I did not understand the cause of this problem.

Please suggest the actions to solve this issue.

please check if the object name has been changed in the load script , can you see this object in a table ?

Actually, i am new and using Data manager to load the data. But the data is available and in the table I provide.

i would suggest to check if there is space between the feilds .. or capitalization
