Error while executing PAL procedures in SAP HANA!

Hi Guys,

When I am executing any of the procedure from PAL library, i get an error:

"Could not execute 'CALL palLnR(DATA_TAB_460, "#CONTROL_TAB_460", RESULTS_TAB_460, FITTED_TAB_460, ...' in 295 ms 570 µs . SAP DBTech JDBC: [2048]: column store error: search table error:  [2620] executor: plan operation failed;required data for execution not found" .

Note: I have created wrapper for the above mentioned procedure.I checked other procedures as well, they produce the same error.

I also have AFL_SYS_AFL_AFLPAL_EXECUTE role assigned to my user.

Regards

Sushant
