CJR2 Planning Error Message

Hi All,

Tried to search threads for this but not found.

While uploading Plan data through CJR2 transaction code - I facing following error message as -

"SER1 840000 cannot be planned (master data)"

Message no. GI522

I have checked and not found anything in Cost Element 840000

What I need to check - can you please suggest ??
