Time out problem

Hi,

I have converted a report program to into /pbs/ program.

The converted /pbs/ program is getting timeout because of these below stmts

LOOP AT IT_BELNR_OTH . "PBS

CALL FUNCTION '/PBS/SELECT_INTO_TABLE' "PBS

EXPORTING "PBS

ARCHIV = 'CFI' "PBS

OPTION = '' "PBS

TABNAME = 'BSEG' "PBS

CLR_ITAB = '' "PBS

SCHL1_NAME = 'BUKRS' "PBS

SCHL1_VON = IT_BELNR_OTH-BUKRS "PBS

SCHL1_BIS = IT_BELNR_OTH-BUKRS "PBS

SCHL2_NAME = 'BELNR' "PBS

SCHL2_VON = ' ' "PBS

SCHL2_BIS = 'z' "PBS

SCHL3_NAME = 'GJAHR' "PBS

SCHL3_VON = IT_BELNR_OTH-GJAHR "PBS

SCHL3_BIS = IT_BELNR_OTH-GJAHR "PBS

TABLES "PBS

I_TABELLE = TAB885 "PBS

EXCEPTIONS EOF = 4 "PBS

OTHERS = 2. "PBS

ENDLOOP. "PBS

please provide solution for avoiding timeout problem.

Thanks & Regards,

Preethi.
