After using  foss_round_off module for Multi Company, when I am trying to validate my invoice, I am getting following error:

error-1:
The requested operation cannot be completed due to security restrictions. Please contact your system administrator.
(Document type: account.account, Operation: read) 

For which I got a solution,
Solution: Record Rules : Account - Account Multi company - permission : Read 

After this It caused another error:
error-2:
The requested operation cannot be completed due to security restrictions. Please contact your system administrator.
(Document type: Journal Item, Operation: write)
 
So i tried following solution:
Solution: Record Rules : Journal - Journal Multi company - permission : Write, Read,Create

Yet its unsolved and showing error-2 again.

Kindly help me in this.
