Here is a simple walkthrough on uploading a file through SAPUI5 interface and saving it as a GOS attachment in SAP system. This example uses purchase order business object (BUS2012). If you plan to use another type of document, you should find corresponding business object and change it accordingly. Create a structure to transfer media […]
Every once in a while, you will encounter ABAP programs taking too long to run. Your duty, as an ABAP developer, is to find the bottleneck. Sometimes it is as easy as debugging the program just once, or even just looking at the code. Sometimes not.. This is where SAT comes in. It is a […]
I believe our previous test on SELECT SINGLE vs FOR ALL ENTRIES did not surprise many of you because I see a tendency towards FOR ALL ENTRIES in programs I encounter. In previous scenario, we were able to access the search table with primary key but this may not be the case every time. Let’s see what happens […]
When all business requirements are met in a development, customer complaints always come down to performance. “Can’t this run any faster?” we always hear. Performance, in a technical point of view, is a broader concept that not just includes execution time, but also optimal use of system resources like memory and network load. But powerful […]
Inequality between length and maximum digit count of packed decimal type causes great confusion even among seasoned developers. ABAPDOCU explains the relation with a fairly complicated formula: Depending on the field length len and the number of decimal places dec, the following applies to the value range: (-10^(2len-1) +1) / (10^(+dec)) to (+10^(2len-1) -1) /(10^(+dec)) […]
Almost every ABAP developer comes to a point where they require obligatory parameters along with user command logic in their selection screens. As you might already know, that’s a problem. Because obligatory parameters demand input on every action of user and interfere with user command logic, which results in a broken selection screen. Let’s see […]
No matter how many times mentioned before (thanks to Rahul Gopinath, Amit Behera, Srinivas Dummu and Mike), I still see sy-subrc check after a function module call without exceptions.
CALL FUNCTION 'RV_INVOICE_CREATE'
vbsk_i = vbsk_i
xkomfk = xkomfk
xkomv = xkomv
xthead = xthead
xvbfs = xvbfs
xvbpa = xvbpa
xvbrk = xvbrk
xvbrp = xvbrp
xvbss = xvbss.
* Error handling
This is so wrong. According to ABAP keyword documentation: If no exception is raised, a call sets sy-subrc to 0. So in the above example, sy-subrc will always be equal to […]
Greetings to fellow SAP ABAP developers from around the world. I have just decided to start a new ABAP blog (yes, yet another) and this first post is here just to share my excitement. So why another ABAP blog? Of course I know there are already many ABAP blogs and tutorial sites who are actually […]
