How to find out structure of internal table?

[Former Member]

Hi

is there any way how to find out name of structure upon which internal

table was created?

i got internal table passed to function module by any table

type. There can be different types of table passed in. Inside of

module a need to find out the structure of table.

I've found a tricky way how to find this information using following

command 'DESCRIBE FIELD dobj INTO td.', but its probably not a correct

way because using this command is not recommended in application

programs.

Is there any function module, or something i can use for getting this information?

Thanks

se37 --> type function module name --> display

in data declartion part the type would be there .

if the FM is calling from any report then in the main report , there would be definition of internal table . search it .

thanks

Hello,

You can make use of the SAP RTTS for this purpose.

Search in SDN for details.

Look at the RTTI classes and their methods, especially CL_ABAP_STRUCTDESCR and CL_ABAP_TABLEDESCR.

Thanks very much

This has solved my problem:

DATA descr_ref TYPE ref to cl_abap_typedescr.

DATA tabname TYPE string.

descr_ref = cl_abap_typedescr=>describe_by_data( itab ).

tabname = descr_ref->absolute_name.
