SAP std Structure

[Former Member]

Hi.

I have to create an ALV report.

among all the standard tables I have some standard SAP defined structures for eg RIHSTPO,MINST and many more...

Regarding DB table like mara i know that I have to create a structure, internal table and WA and then fetch the data from DB table and populate ITAB for generating ALV etc etc.

Now please tell me when I have Structure and not DB table, How to display data? for eg, in RIHSTPO i have to display MENGE as a column in ALV, how can I do so?

In my selection screen also I have to create a select-option field of type structure, can I write, select-options: klart for rmclf-klart . ? in this case how to declare the structure, can declare same as table? i.e. TABLES: rmclf or declaration for structure is different ?

Please explain the procedure with small sudocode.

Thanks in advance

Hello,

Structures are just a layout and doesnot contains any data.

If you are asking about creating a internal table which is type a already existing structure in DDIC, you can just create it just like you create a internal table like:

data: t_table type standard table of <structure_name>.

You can also create a structure in your own program as:

Structure Declaration.

types: begin of ty_struc,

matnr type matnr,

-

---

,

-

---

,

end of ty_struc.

Internal table Declaration.

data: t_table type standard table of ty_struc.

Also, you can declare the select option i.e. selection screen parameters using the fields of structure.

Hope that helps.

Thanks,
