Conversion HR_INFOTYPE_OPERATION to RFC-BAPI

Dear All,

I want to convert  HR_INFOTYPE_OPERATION to RFC Enabled BAPI ZHR_INFOTYPE_OPERATION.

I have copied the above function module to ZHR_INFOTYPE_OPERATION.

There is a importing parameter " RECORD" which is of type ANY, in function module  HR_INFOTYPE_OPERATION.

I am making this function module as Like Char2000.

When i am making this function module as RFC enables option and running, then i am getting a dump.

"The following syntax error was found in the program SAPLZFG_HR_DS_BAPI :

""CHAR2000" must be a flat structure. You cannot use internal tables, s"

"trings, references, or structures as components."

And in a BAPI its not allowing to have any type as generic.

Can anyone let me know, as i need to call this function module at other place.

Thanks,

A Sustainer
