Setup the Rate Type Value

Hi All

While I am loading the master data for account dimension I need to setup the Ratetype property value as per the below condition.

I am loading the GL number ranges between 100000 to 499999 and I setup the Ratetype mapping as below:

RATETYPE = *IF(ID(1:5)=*STR(00001) then *STR(EOM);ID(1:5)=*STR(00002) then *STR(EOM);*STR(AVG)) and it works fine.

Now the requirement is as below:

Now there is few gl accounts between this number ranges those are identified randomly (near about 100 gl's) for setup the Ratetype value as HIST.

Please suggest how can i achieve this?

Regards
