Splitting records in internal table

Dear All,

I am facing a problem while passing values to a function module i am getting an error 'DBIF_RSQL_INVALID_RSQL'.

I found that i am passing too many values to that Function module from an internal table. So now iam getting around 20000 records in this internal table and i need to split as 4000 records as a batch and need to pass, how i can achieve this.

With regards,

Tony.
