BPC NW 10: avoid expansion of report, keep fixed layout

hi bpc gurus:

I have a epm report with account and brand on rows and time in columns, on brand I changed the function to fix a brand to an account, for example:

Account
Brand
2015.01 2015.02
...
2015.12
ACC1 01



ACC2 05



ACC3 17



ACC4 23

but when the report refresh it makes a mix of account and brands like this:

Account
Brand
2015.01 2015.02
...
2015.12
ACC1 01



ACC1 05



ACC1 17



ACC1 23



... ...



ACC4 01



ACC4 05



ACC4 17



ACC4 23

is there a way to avoid the expansion of the report and keep the fix layout?
