Blank language key

Dear Experts,

I received the following error message while trying to load text for info object 0S_OPERAT and 0OPERATION.

The data record 1 & with the key '00000600000200600150 &' for characteristic 0S_OPERAT & has a blank language key.

A similar message was also received for 0OPERATION.

I looked at the PSA file, and the language is blank.

What do I need to do to resolve this? Any suggestions and input would be greatly appreciated.

Thank you in advance for your help!

Andrew
