Project System - Cost Element Default as 400000 in Material Assignment for Network Activity

[Tanuj_Kelkar]

Hello All Experts,

I am facing an issue, while assigning material for network activity, Cost Element is getting defaulted to 400000. 

See below image - 

 But when I checked the settings for Network Profile in OPUU, its all blank. No default cost element has been maintained there for 0000002 which I am using. 

Can someone expert tell me how can I change this to another one  ? Or From where it is getting defaulted ? 

Thank you for your time. 

Regards,

Tanuj K.

For components with material masters the cost element will come from MM account determination.  Start with the Valuation Class on the Accounting 1 tab, then you will have to follow the config for MM Account Determination.
