Hi Experts,

when executing the following report. couple of errors r displayed..pls correct the code.

1) "IT_MARA" is not type-compatible with formal parameter "IT_MARA".

2) "IT_MARA" is neither specified under "TABLES" nor defined as an internal table.

DATA: MARA TYPE MARA.

*provide data objects

DATA: OBJ TYPE REF TO Y_CL_INTERFACE,

IT_MARA TYPE ZMARA,

WA_MARA TYPE MARA.

*provide selection screen

SELECT-OPTIONS: S_MATNR FOR MARA-MATNR.

*provide object

START-OF-SELECTION.

CREATE OBJECT OBJ.

*call the method.

CALL METHOD OBJ->Y_IF_INTERFACE~SELECT_METHOD

EXPORTING

P_MATNR_LOW = S_MATNR-LOW

P_MATNR_HIGH = S_MATNR-HIGH

IMPORTING

IT_MARA = IT_MARA

WA_MARA = WA_MARA.

*display the data

LOOP AT IT_MARA INTO WA_MARA.

WRITE:/ WA_MARA-MATNR,

WA_MARA-ERSDA,

WA_MARA-ERNAM,

WA_MARA-MATKL,

WA_MARA-MEINS.

ENDLOOP.

and also when trying to activate the class too the following error is diplayed

"IT_MARA" is not an internal table - the "OCCURS n" specification is missing".

please guide me.

hi,

Your table declaration part is wrong....

wherez that zmara coming from ? And for internal table you should have ' type standard table ' in your table declaration....

These are simple errors. Fundamentals...
