data conversion functions ??

Hi,

whats the function to convert a numeric data to char ??

I have a field value which is numeric and when I use it in my BDC program I get a runtime error

CONVT_NO_NUMBER

Unable to interpret "/" as a number.

On debugging, I could see in the code that NODATA is represented as "/" and when it is being compared with my numeric field data, this mismatch is reported. So I think it would be right for me to pass on the value after conversion. the statement currently looks like

perform bdc_field using 'RF022-GJAHR'

bkpf_rec-gjahr.

where gjahr contains data such as 2004, 2005 etc.

Please help..

thanks
