[former_member828350]

I am a new ABAP Learner and don't know so much about ABAP but I'm trying to learn new things.
Currently while writing a program I am getting this error while executing :-

The current ABAP program "SAPLSLVC" had to be terminated because it has

come across a statement that unfortunately cannot be executed.

Code:-

REPORT ZYZ_TEST.

TABLES ZSTEST.

DATA: IT_ST TYPE TABLE OF ZSTEST,
WA_ST TYPE ZSTEST,
IT_FINAL TYPE TABLE OF ZSTEST,
T_MARKS TYPE I,
DAYS TYPE P VALUE '365.25',
AGE TYPE I.

SELECT-OPTIONS: S_ID FOR ZSTEST-STUDENT_ID OBLIGATORY,
S_DOB FOR ZSTEST-DATE_OF_BIRTH NO INTERVALS NO-EXTENSION.
SELECT * FROM ZSTEST INTO TABLE IT_ST
WHERE STUDENT_ID IN S_ID AND DATE_OF_BIRTH IN S_DOB.

IF sy-subrc <> 0.
MESSAGE ' Please Provide Student ID in between 110 and 120' TYPE 'E'.
ENDIF.

LOOP AT IT_ST INTO WA_ST.
T_MARKS = ( WA_ST-CHEMISTRY + WA_ST-PHYSICS + WA_ST-MATHS ).
AGE = ( SY-DATUM - WA_ST-DATE_OF_BIRTH ) / DAYS .
WA_ST-TOTAL_MARKS = T_MARKS.
WA_ST-AGE = AGE.
APPEND WA_ST TO IT_FINAL.
ENDLOOP.

MODIFY ZSTEST FROM TABLE IT_FINAL.


TYPE-POOLS: SLIS.

DATA: IT_FIELDCAT TYPE SLIS_T_FIELDCAT_ALV,
WA_FIELDCAT TYPE SLIS_FIELDCAT_ALV.

PERFORM WA_FIELDCAT USING 'Student_ID' 'Student ID'. "Fieldname in the data table and Column description in the output.
PERFORM WA_FIELDCAT USING 'Student_Name' 'Student Name'.

OTHERS = 2.

FORM WA_FIELDCAT USING VALUE(P_FIELDNAME)
VALUE(P_SELTEXT).

WA_FIELDCAT-FIELDNAME = P_FIELDNAME.
WA_FIELDCAT-TABNAME = 'it_final'.
WA_FIELDCAT-SELTEXT_M = P_SELTEXT.

APPEND WA_FIELDCAT TO IT_FIELDCAT.

CLEAR WA_FIELDCAT.
ENDFORM.

Waiting for positive responses and Thanks in Advance.

Use CODE formatting to share your code, to make it more readable:

Hello starboysb2503

Use capital letters to populate FIELDNAME and TABNAME in the ALV field catalog. Try the following quick fix

FORM WA_FIELDCAT USING VALUE(P_FIELDNAME)
VALUE(P_SELTEXT).

WA_FIELDCAT-FIELDNAME = P_FIELDNAME. TRANSLATE WA_FIELDCAT-FIELDNAME TO UPPER CASE.
WA_FIELDCAT-TABNAME = 'IT_FINAL'.
WA_FIELDCAT-SELTEXT_M = P_SELTEXT.

APPEND WA_FIELDCAT TO IT_FIELDCAT.

CLEAR WA_FIELDCAT.
ENDFORM.

Best regardsDominik Tylczynski

Thanks for your quick response.

FYI earlier this code was working fine but I don't know why It's not working now. 🙁

You can find answers in the forum. The field names must be given in capital letters.

You'd better not use REUSE_ALV_GRID_DISPLAY -> Use the modern CL_SALV_TABLE, this error doesn't happen.

Please edit your question (there's a button to edit your question) and use the button CODE to make your code legible, as already requested by Dominik.
