Data type conflict when calling a function module

Hi. Good Day.

Requirement- Need to convert .XML output into PDF form. So that I am using 'CONVERT_OTFSPOOLJOB_2_PDF' function module.

In the exporting parameter of mentioned FM, src_spoolid is attached with TSP01-RQIDENT data type.

I have created one structure job_output_info which is having spoolids standard table(table type).

Now I need to fetch the data from standard table TSFSPOOLID which is attached with structure SSFCRESCL into one variable. Not able to do it.

Need your help. Thank you
