CDS View with arithmetic CASE-Expression

[former_member207964]

Hey Experts,

i'm developing a CDS-View in ABAP for HANA and i need a CASE-Statement with an arithmetic expression in it.

Error on above image is unexpected word "(".

I have also tried a few other ways like casting or subtracting in a between clause but nothing works.

Looking forward to your answers.

Simon

Hi Simon,
please find the restrictions in CDS CASE expressions in ABAP Keyword Documentation.

So, I think you'll have to use a workaround like a view-on-view, wherein the underlying view calculates the field you'd like to use as right hand side (rhs) of the conditional expression.

Cheers,

case

when fkimg > 10

then 'dummy'

when netwr between 10 and 100

then 'dummy'

else

'fit'

end as invoiceuse ,

i have used this above code to build cds view it dnt throwed any error

and when you want to compare same field then try like,

case fkimg

when 0

then 'bad'

when 10

then 'good'

else

'better'

endcase as result.

Thanks Jasmin for your replay.

Using calculated fields in the same view again is also not possible?

bap.kwmeng - vbap.untto as calc,

case when bmeng >= calc and bmeng < vbap.kwmeng then 1

Thanks
