Customer Exit Variable reverting to ABAP debugger rather than giving output in Report screen RSRT

[former_member687642]

I have created customer exit variable for Calendar Year and used Enhancement RSR00001 and wrote code in EXIT_SAPLRRS0_001

DATA: L_S_RANGE TYPE RSR_S_RANGESID.

CASE I_VNAM.
WHEN 'ZVAR_CCEXT'.
CLEAR L_S_RANGE.

L_S_RANGE-LOW = 'SY-DATUM+0(4)'.

L_S_RANGE-SIGN = 'I'.

L_S_RANGE-OPT = 'EQ'.

APPEND L_S_RANGE TO E_T_RANGE.

ENDCASE.

which is syntactically correct but when i run report in RSRT it is just reverting to ABAP debugger screen (screenshot attached) rather than giving output.Please help me what to do to resolve this.

Thanks in Advance.

I used L_S_RANGE-LOW = 'SY-DATUM+0(4)' but sy-datum should not be in single quotes else treated as text and size mismatch occurs which inturn takes us to abap debugger screen.

You must populate I_STEP:
