FI12 "Specify the key within the work area, Message no: SV033" House Bank

Hi All

While creating a house bank , its giving me this error : "Specify the key within the work area message no: SV033 " . I am creating a house bank with the name of "CITI1" .

Now its not accepting more than 5 letters/digit .

If i delete the last digit which is 1 , then it lets me create the house bank , but its not even accepting a digit / letter /alphabet more . and the client's requirement is House bank name as : "CITI1"

I have checked the country specific settings in OY17 and even in OB32 , but its not helping me out.

I would request you all , kindly intervene and help .

I have also checked the field HBKID in se11 , there the length specified is 5 and data type is CHAR .

Please suggest me something ......
