Until recently, ABAP has never been one for big collaborations.

Eclipse ADT puts ABAP Doc to good use

ABAP Doc is an excellent way of integrating documentation into the code.

The magical F2 in Eclipse ADT

Eclipse ADT calls it Code element information.

Use BASE to not ruin what you already have

We used to use the APPEND and INSERT commands to add rows to internal tables. Now that ABAP has grown, we can use VALUE, REDUCE, CORRESPONDING, etc. But what if the internal table already has rows and we don’t want to lose them?

INNER JOIN instead of FOR ALL ENTRIES

A while ago I showed you that you could SELECT from an internal table. And then I asked myself: if that is possible, shouldn’t INNER JOIN be possible too?

Did you know that your ABAP programme can copy content to your operating system’s clipboard?

SELECTing from an internal table

Now you can SELECT from an internal table.

SELECT SINGLE vs SELECT UP TO 1 ROWS

Man, this is one of those endless discussions that will never get anywhere. Ditto trying to decide if you deserve to go on living if you put pineapple on your pizza or Philadelphia cheese on your sushi.

Call SM30 or SM34 from a function module

If you want to call the SM30 from a program you can use CALL TRANSACTION but there is a simpler way.

Use a dictionary instead of IF or CASE

The fewer IFs and CASEs the better, right? Every branch of an IF or a CASE is an exception. And we like rules better than exceptions. Here’s one more technique to achieve that.

SAP messages are all managed centrally through the SE91 transaction, but can appear to a program in a variety of formats.

SELECT single record using an incomplete key

I was always told that, when selecting a single record, I should use UP TO 1 ROWS whenever the key was not fully provided. My elementary school teacher told me that I should always aks why: why? Nobody ever told me why.

Use & in SAPSript texts

Let’s say you want to show an url in a SAPScript layout. You place the url in a SAPSCript text and assume everything will work fine. Because most times everything does work fine. It’s just that sometimes…

Clean data declarations

While writing code, you should always keep present how easy it will be to maintain. This is particularly important in data declarations. And so easy to do right.

SELECT FOR UPDATE

When you’re going to modify existing records of a database table it is common to first SELECT them to see how they are and only then UPDATE them with what they will be.
