Program the program programming
One of the few things that separates us humans from all the other animals is our ability to think about thoughts.
A sparrow may think I’m scared, I’ll say chirp chirp chirp and, as a direct consequence, whoever stands close to it will hear chirp chirp chirp.
Use the "where used" tool in a program
The “where used” tool is very dear to any ABAP developer. Through it one can find out where a given object is used. Doesn’t look like much but we all know how important this is.
Class CL_GUI_FRONTEND_SERVICES
Class CL_GUI_FRONTEND_SERVICES is commonly used to upload and download files from and to the user’s local computer. But it can do many more good things. For example:
SAP can take selfies!
I just found out that SAP can take selfies. I still don’t see why one would need it. But that’s understandable because I never really understood the need for selfies anyway.
Here’s how SAP can take a selfie:
Do you know the ASCII code for CR_LF and its buddies?
I don’t.
And I don’t want to. Why waste memory on stuff like that?
And I don’t need to because ABAP has a class just for that.
SELECT from a set of known values
Someone asks you to select records based on a criteria for which you’ll have a small set of known values which you’re told will never change. Did you know you can do it directly in the SELECT?
You can save variants in SE16N
And that’s it really. That’s the whole tip right there at the title. This has always been right under your nose but you probably never thought about it: you can save variants in SE16N. And they can even be user-specific. So useful and so little known. Thank you Sérgio Fraga for the tip. Thank you Cloudtail for the photo. Greetings from Abapinho.
Limitar execução em background ou foreground
You’ve developed a report which you know will take over 12 hours to run. So you don’t want anyone to try to run it in foreground. I’ll show you a way to make sure it doesn’t happen.
How to sabotage standard texts
Some times I don’t like the names SAP gave to things. So I change them.
For example, one day I was very angry and thought all customers were parasites.
So I did the following:
Formating variables when concatenating strings using <i>pipes</i>
Pipes are the new trend when it comes to manipulating strings:
str = |Hi { sy-uname }, | &
|today's date is { sy-datum }.|.Besides looking cool, it’s way more practical than using the dreaded CONCATENATE.
But I only recently found out that you can directly apply formatting to the variables:
Is the GUI available?
To check if a program is running in background usually one takes a peek at SY-BATCH. SY-BINPT can also be used to check if the background program is a BDC session. You usually check one of these.
There is a similar but not exactly equal question, though. How do you ask if the GUI is available? Most times both questions will have the same answer. But not always.
It’s like saying the Sun can be seen during the day while the Moon can be seen during the night. If the sky is cloudy you won’t be seeing them.
How to avoid timeout when running a program
Usually SAP systems have a predefined time limit for running a program interactively. If the program takes longer to run than that you’ll get a runtime execution error. A dump.
In ABAP's name, I baptize you
When we learn ABAP, we are taught a series of rules on how to name variables. Not everyone uses the same rules but, still, some strict rules are shared between many people:
-
Local variables must start with L: L_BUKRS;
-
Global variables must start with G: G_MODE;
-
Internal tables must have T_: LT_MARA;
-
Structures must have S_: LS_MARA;
-
Object references must have R_: R_CUSTOMER;
-
input parameters must start with I, output with O, changing with C and returning with R.
-
And the most stupid of all, field-symbols must start with FS_: <FS_MARA>.
In the early XXI century those rules made some sense (except for the field-symbols on, which was, and still is, as stupid as writing ‘pencil’ in all our pencils). Today they don’t make much sense anymore. Let me explain.
Abapinho Dev Tools: Translator
Nuno Morais has developed another very useful tool to help simplify mass translations of most SAP objects. The toold is not for automatic translation between two languages. Instead, it has the following features: Export an Excel file with texts Import an Excel file with texts Copy texts from one language into one or more languages Create a transport order with the changed texts
