Error while calculating Cost( Log- Material type does not exist . MsgNo. -179 financial accounting(CK).)

Hi Experts,

We have created 4 material to a internal activity in the network earlier, but when tried to create 5th material to same activity at the time of saving it is giving an error.

Error- "Error while calculating Cost, log is deleted when saving do you want to save?".

When I checked the log in CJ20N, it is showing following reasons- Material type does not exist . MsgNo. -179 financial accounting(CK).

I just want to clarify that the first material of the activity and the material which is giving error have same General data are same purchase data.

Can this error be related to budget?

Or some network related issue?

Please suggest....

Thanks and Regards,

Roshan Malaruthu.
