Could you please share the field catalog that is being populated for that field and the method that is being called for displaying ALV.

If posiible please also share the standard report and form which is throwing error (from runtime debugger).

Hi PranavJeeth,

this is my field catalog.i'm just showing one field.

PERFORM set_field USING:

FIELD SHORT TEXT LONG TEXT OUTLEN TYP FMT SUM HID

'STPRS' 'STD.PRICE ' 'STANDARD PRICE ' '00011' 'P' ' ' ' ' ' ',

FORM set_field USING pv_fieldname TYPE c

pv_descr_s TYPE c

pv_descr_m TYPE c

pv_length TYPE c

pv_inttype TYPE c

pv_format TYPE c

pv_sum TYPE c

pv_hide TYPE c.

CLEAR gw_fieldcat.

gw_fieldcat-fieldname = pv_fieldname.

gw_fieldcat-seltext_s = pv_descr_s.

gw_fieldcat-seltext_m = pv_descr_m.

gw_fieldcat-outputlen = pv_length.

gw_fieldcat-inttype = pv_inttype.

gw_fieldcat-no_out = pv_hide.

CASE pv_format.

*-- Prices must have corresponding currency for format purposes

If no currency field is needed (fixed currency), use
GW_FIELDCAT-CURRENCY instead of GW_FIELDCAT-CFIELDNAME

WHEN 'P'. " prices

gw_fieldcat-currency = 'MYR'.

gw_fieldcat-do_sum = pv_sum.

when i excute report is ok.but when we clcik on alv toolbar runtime error occuring.when i run debugger,the code like this

if gs_fc-tech_form ne 99.

gs_out-hlplen = strlen( <field> ).

endif.

when i click on field the values like this

<field> = 100

gs_fc-tech_form = 90.

please suggest on this issue.
