Hi Alex,

It seems you are persistently trying to get the answer to the question which cannot be answered.

Neither single nor double exist in current SAP release (at least they are not defined as such). DEC on the other hand is a type which has some range. So I think you want to get info about data object of specific type not this data type itself. It is because for data type the lenght is not fixed so how would the system know what you are asking for. So the below is only available

data gr_elemdescr type ref to cl_abap_elemedescr.
data g_my_var(10) type p decimals 4. "existing data object to be checked

gr_elemdescr ?= cl_abap_typedescr=>describe_by_data( g_my_var ).
write: 'Length ', gr_elemdescr->length,
           'Dec places', gr_elemdescr->decimals.

Regards
