Bypassing the invalid character # while loading data into BW

Hi Experts,

While i was loading data into BW i encountered the invalid character # .so i had to go to PSA correct it and then push the data to the info provider. But is there any way to bypass this i.e. in RSKC .But i already have ALL_CAPITAL in RSKC however it is not allowing the character # into BW.

I will definitely reward points if the answer is useful ....

Thanks

Santosh ...
