Dynamically changing ALV grid output

Former Member — Mon, 21 Aug 2006 07:46:45 GMT

Hi all,

i have a selection screen on which there are 6

checkboxes. depending on the combination of check

boxes selected the no of colums in the ALV grid output

should change.

for eg. if check box 3 , check box 5 , and check box 6

are selected then a fieldcatalog should be created which

will have fields corresponding to check box 3, then 5

and then 6 .

if only 5 ,6 are selected columns corresponding to only

them should be shown.

i cant write the code to populate fieldcat for each

of the combination of the 6 chkbox.

is there any other way to do it??

Regards,

Tarang

HI,

You can use <b>'NO_OUT'</b> option to hide columns depending on selection. In this way you have to build only one field catalog.

Hello,

U can try like this. When u r populating the field catalog, U check for the checkbox values.

IF P_CHK1 = 'X' and P_CHK2 = 'X' and P_CHK3 = 'X'.

Populate the fieldcatalog values for the particular field.

ENDIF.

If useful reward.

Hi,

Based on your Check box selection , use the Fieldcat option <b>TECH = 'X'</b>.

if check = 'X'.
fieldcat-tech = 'X'.
endif.

TECH = 'X' will not show the column in the output.

hi HRA,

but this way also i will have to write

several if statements like.

1. if chk1 = 'X'

2. if chk1 = 'X' and Chk3 = 'X'

3. if chk3 = 'X' and chk 7 = 'X'.

and so on...

so there will be (2 raise to 6 )i.e 64 combinations

any other way

Hello,

Ya that's true that you can't write statment for all but you can proceed in this way.

Make one internal table,

data: begin of it_col occurs 0,

check(10),

field(10),

end of it_col.

Fill this table as,

it_col-check = 'CHK1'.

it_col-field = 'FLD11'.

append it_col.

it_col-check = 'CHK1'.

it_col-field = 'FLD12'.

append it_col.

it_col-check = 'CHK2'.

it_col-field = 'FLD13'.

append it_col.

it_col-check = 'CHK2'.

it_col-field = 'FLD11'.

append it_col.

Now,

depending upon your selection of checkboxes,

if chk1 = 'X'.

loop at it_col where check = 'CHK1'.

populate your field catalog.

endloop.

endif.

if chk2 = 'X'.

loop at it_col where check = 'CHK2'.

populate your field catalog.

endloop.

endif.

At last you will be having your fields in catalog.
