error in BDC Program create routing 'ca01'

Hi Experts,

I'm creating BDC code for create routing 'CA01' code. I considered all the mandatory fields but when i'm trying to enter a value(1,2,3,4 etc.) for the field ' PLKOD-STATU' it gives me number conversion error & program gets terminated.

The field 'STATU' has data type ;CHAR with 3 digits & it has search help attached to it having values 1,2,3,4 etc. So, in excel sheet i'm entering values for the same field as 1,2,3...even tried 001,002,003.... but its not working. Can you help me to remove this bug?

Thanks,

Sumedh
