Spaces in element names?

Hello,

we renamed some companies adding a space and some text.

For example company "64" was renamed in "64 TA"

After renaming we started to have issues in the rules like if Onestream does not recognize the space.

This is  a sample error message we receive.

Summary: Unable to execute Business Rule 'WES_Rules'. Invalid script 'A#4028_02:O#Elimination:F#None:I#64 TA:U1#None:U2#None:U3#IC_Details:U4#INTERCOMPANY:U5#None:U6#None:U7#None:U8#None' near '64'.

Is there some hidden contraint in Onestream that prevents clients to create element with spaces?

By the way, do you know if there is any workaround to overcome this issue in the rules? because I belive our custmer will not accept to go back to the simple company code.

Thanks in advance

Marcello
