Editable ALV Quantity/Decimal field

[Former Member]

Hi,

I have one column in ALV output which is editable .I have defined that in this way:

data :input type resb-bdmng.

fieldcatalog-fieldname = 'INPUT'.

fieldcatalog-seltext_m = ' Scrap'.

fieldcatalog-col_pos = fieldcatalog-col_pos + 1.

fieldcatalog-input = 'X'.

fieldcatalog-edit ='X'.

APPEND fieldcatalog TO fieldcatalog.

CLEAR fieldcatalog.

But if we edit the field in the output it gives error : " Too many decimal places ( maximum 0)"

If we add fieldcatalog-datatype = 'DECIMAL'. then it works fine but in that case it throws dump for toolbar button " Export to the local file " Its functinality is copied from standard interface SAPLKKBL program The dump is The current statement requires chaarater data type object .It cant take decimal fieldcatalogtype . If we remove fieldcatalog-datatype = 'DECIMAL'. then this button works fine but in this case the first error comes "Too many decimal places ( maximum 0)"

Please suggest how can I remove first error without setting fieldcatalog-datatype = 'DECIMAL'. property.

Will definetly ..... if its helpful

Try passing reference table and field in your fieldcat.

fieldcatalog-ref_fieldname = 'BDMNG'.

fieldcatalog-ref_tabname = 'RESB'.

It works . But in this case the column name is coming as the refernce field name which I dont want .

I want it fieldcatalog-seltext_m = ' Scrap'.

Please suggest

It might be bcoz of length probelm of output field scrap .

us fieldcatalog-outputlen = '30' like that

hi,

This is a common problrm when yu want to display the values in decimals...if the datatype is any other than character, if u try to export to file,it will throw dump.change the datatype into character in ur internal table itself ,,then calculte the values in decimals and insert to this fieldand display.Now it will allow edit and wont throw dump
