Hi Pavan,
Check the configuration once again. I am not aware of that CIN related forms.
SPRO > Logistics - General > Tax on Goods Movements > India > Business Transactions > Subcontracting > Subcontracting Attributes
However you have the option to implement the implicit enhancement for particular form routine.
Start of the routine you can call the open form once again and pass the customized form.
Condition is required to call your own form. I think you can check with some conditions.
If CONDITON - CHECK
call open form CALL FUNCTION 'OPEN_FORM'
EXPORTING
APPLICATION = 'TX'
DEVICE = 'PRINTER'
DIALOG = 'X'
FORM = Customized form name.
IMPORTING
RESULT = RESULT
EXCEPTIONS
CANCELED = 1
DEVICE = 2
FORM = 3
OPTIONS = 4
UNCLOSED = 5
OTHERS = 6.
IF SY-SUBRC NE 0.
MESSAGE E888.
ENDIF.
ELSE.
CALL FUNCTION 'OPEN_FORM'
EXPORTING
APPLICATION = 'TX'
DEVICE = 'PRINTER'
DIALOG = 'X'
FORM = 'J_1I_57F4'
IMPORTING
RESULT = RESULT
EXCEPTIONS
CANCELED = 1
DEVICE = 2
FORM = 3
OPTIONS = 4
UNCLOSED = 5
OTHERS = 6.
IF SY-SUBRC NE 0.
MESSAGE E888.
ENDIF.
ENDIF.
