Hi,

Can anyone help re write my case statement please so it works?

proc sql;

create table adjusted_movement as

select *,

case when ltd_allocations gt runnning_sum then 'current' else if ltd_Allocations + weekly_movement gt dealt_amount

then running_sum - ltd_allocations else weekly_movement end as adjusted_movement

from

Allocate_rates_LTD_Allocations;

quit;

Try:

proc sql;

create table adjusted_movement as

select *,

case when ltd_allocations gt runnning_sum then 'current' when ltd_Allocations + weekly_movement gt dealt_amount

then running_sum - ltd_allocations else weekly_movement end as adjusted_movement

from

Allocate_rates_LTD_Allocations;

quit;

544 when ltd_allocations gt running_sum then 'current'

545 when ltd_allocations + weekly_movement gt dealt_amount_ then running_sum - ltd_allocations

546 else weekly_movement end as adjusted_movement

547 from

Yes, thats because the logic of the second when results in a numeric value, the first 'current'. You need to decide what you want the outcome to be, for instance, if the column is to be text then:

proc sql;

create table adjusted_movement as

select *,

case when ltd_allocations gt runnning_sum then 'current'

when ltd_Allocations + weekly_movement gt dealt_amount then put(running_sum - ltd_allocations,best.)

else put(weekly_movement,best.) end as adjusted_movement

from Allocate_rates_LTD_Allocations;

quit;

If its to be numeric then you can't have current, maybe:

proc sql;

create table adjusted_movement as

select *,

case when ltd_allocations gt runnning_sum then 99999

when ltd_Allocations + weekly_movement gt dealt_amount then running_sum - ltd_allocations

else weekly_movement end as adjusted_movement

from Allocate_rates_LTD_Allocations;

quit;
