Subject: Confusion in looping tables in ABAP
Hi, you may want to post this question in sap-newbies As this is obviously a question from a training course. The best way to learn is not to get solved your questions, but to know where to find the answers. So... That's what I'll help you to get:
In order to solve your question, you may want to:
1. run ABAPHELP tcode with loop at, select
2. visit HELP.SAP.COM
3. GOOGLE!!!!!!
4. visit the home pages of this and other groups and SEARCH there (there is a button you can gently use).
Just to be polite: an INTERNAL TABLE is like a list of rows of the same structure (behaves like an array of rows with sort and read by key functionality). LOOP is the way you use to navigate the whole table, on a record by record basis. (of course, you have ways to filter records) . The structure of the row can be whatever you want. You define it. In theory, you can't have different row formats in an itab. In practice... with knowledge and experience... it is a flexible tool...
to fetch data from a db table you use.... (I must be getting old...) SELECT (abaphelp and a few minutes reading can through a lot of light on your doubts...)
(IN UPPERCASE you have what you'd have to look for in abaphelp) Now you have everything you need TO START.
HTH
Horacio. |
