Hi sivaranjhani,

Here is an example of how to call a function dynamically (note: comments were added to an existing example from the standard help)

REPORT ZDANY_DYN_FM_CALL.

*The constants and structures required to use the dynamic function call

*is stored in the type pool ABAP.

type-pools abap.

*This is the name of the function you want to call.

data NAME type STRING value `READ_SPFLI_INTO_TABLE`.

Parameter table, where you store all parameters, importing, exporting

and changing data PARA_TAB type ABAP_FUNC_PARMBIND_TAB. data PARA_LINE like line of PARA_TAB.

Exception table to handle the exception that can occur during the

execution of the function

data EXCP_TAB type ABAP_FUNC_EXCPBIND_TAB.

data EXCP_LINE like line of EXCP_TAB.

data CARRIER type SPFLI-CARRID.

data JTAB type SPFLI_TAB.

CARRIER = 'XYZ'.

Name of the first parameter

PARA_LINE-NAME = 'ID'.

type of the first parameter, could be :

abap_func_exporting value 10,

abap_func_importing value 20,

abap_func_tables value 30,

abap_func_changing value 40.

PARA_LINE-KIND = ABAP_FUNC_EXPORTING.

*We need the datatype of the parameter to pass

get reference of CARRIER into PARA_LINE-VALUE.

append PARA_LINE to PARA_TAB.

*Same thing for parameter 2

PARA_LINE-NAME = 'ITAB'.

PARA_LINE-KIND = ABAP_FUNC_IMPORTING.

get reference of JTAB into PARA_LINE-VALUE.

append PARA_LINE to PARA_TAB.

*Now we create the possible exceptions

EXCP_LINE-NAME = 'NOT_FOUND'.

EXCP_LINE-VALUE = 1.

insert EXCP_LINE into table EXCP_TAB.

EXCP_LINE-NAME = 'OTHERS'.

EXCP_LINE-VALUE = 4.

insert EXCP_LINE into table EXCP_TAB.

*... and we dynamically call the function with the parameter-table and

exception-table addition

call function NAME parameter-table PARA_TAB exception-table EXCP_TAB.

We check the result codecase SY-SUBRC. when 1. message id SY-MSGID type SY-MSGTY number SY-MSGNO. when 2. message E888(SABAPDOCU) with 'Error in function module'.endcase.

Reward ponits if helpful..
