Hi,
The simpliest workaround (not sure if efficient) will be create global temporary column table to store the ABAP internal table data. This temporary table will be used to hand data into your procedure.
So you always need to perform the following order:
1. truncate data in your global temporary table in HANA;
2. insert ABAP internal table data into the temporary table in HANA;
3. call your procedure using the global temporary table as input table
