Function Module to Map a Deep Dictionary Structure : CATSXT_GET_DDIC_FIELDINFO

Having been asked to make some changes in a BADI, I was confronted by SAP Standard Structure MDG_BS_BP_S_EXTERN which is a structure made of lots of other structures. I'd been asked to make changes to content of a field, but it wasn't obvious where in the multi-structure environment the field resided. 

One option was to methodically go through all the structures looking for the relevant one. I thought there must be a way to explode this...

and so function module CATSXT_GET_DDIC_FIELDINFO...

Takes input of MDG_BS_BP_S_EXTERN  (which, if you look at in SE11 just has some structures:)

And explodes to the more realistic 1.6k ish fields:

Do It Yourself EWB Programming

 So I recently had to perform tasks described in note: https://launchpad.support.sap.com/#/notes/488765 the EWB - Engineering WorkBench... now "Do it yourself" is an interesting Business Model... on the one hand, you're giving people the flexibility to create and craft as they see fit... on the other hand, one might be thinking "Come on SAP, there should be a BAPI there..."

They come close, but it seems not as simple as a BAPI. Why do they not just tie the steps they've described up into a BAPI... like "To make a change, first you need to do the locking, reload, then make the change..."???

Another thing they note is "If you have difficulties using the API, we would like to support you within consulting."

I bet you would.

Anyway, here's some code that removes a Sequence from the "Sequences" part of CA02.

PLPO - PLFL link

Okay,  I know the Select * s are inefficient, but makes the code more readable.

Had been struggling to work out what made the Sequence Items in CA02 disappear when we "Delete" one of the lines. Not sure why PLPO doesn't get it's own LOEKZ updated, but hey...

This finds ACTIVE sequence lines for Routings.

Calling MS-SQL stored procedure from ABAP

My SAP System had to call a stored procedure on a 3rd party MS-SQL database. As suggested by many blogs, I used DBCO to maintain the parameters of the database... (kind of a BASIS job, but anyway...)

Then found I could use the DBCursor mechanism to retrieve to a table... but my 3rd Party guy didn't want to use SELECT statements, he wanted to use a stored procedure.

Turns out you can use DBCursor to select from an Stored Procedure too...

We had to "qualify" the database name, pre-empting the stored procedure (see highlight)

data: ls_output type tty_output,                        "This bit will differ in each Stored Procedure,
      lt_output type TABLE of tty_output.         " so I have not put it in!! 

EXEC SQL.
  CONNECT TO 'CO11' AS 'V'
ENDEXEC.
EXEC SQL.
  SET CONNECTION 'V'
ENDEXEC.
EXEC SQL.
  open dbcursor for
  EXEC [DatabaseName].[dbo].[StoredProcedureName] 700, '2041', 'S1233124'
endexec.
DO.
  EXEC SQL.
    FETCH NEXT dbcursor INTO :ls_output-SerialNumber,
                             :ls_output-MACID
  ENDEXEC.
  IF sy-subrc = 0.
    APPEND ls_output to lt_output.
    clear ls_output.
    CONTINUE.
  else.
   exit.
endif.
enddo.

SMARTForms Colour Border Gotcha

This just foxed me for an hour :(

When changing the border colours/widths/settings of a table (or I guess, a window, graphic, whatever) you have to re-create the entire border.

Weirdly, this means you can set the width to 5mm, and the colour to Green, and add a top border...

Then a 3mm brown left border, then a 10 TW lower border...

I was changing widths/colours of existing borders, but not re-creating. So you CAN'T just change them... (MEME ALERT)

VOFM Copy Routine being ignored!?

I found that using the Modification Assistant meant that the VOFM changes were not registered, but switching it off got the object activated and RV45C601 inserted into the main RV45CNNN program.

Prior to that, I'd been running RV80HGEN and all that jazz, RV45C601 had been created, and had code in it, but because it hadn't been listed / registered / recorded in RV45CNN, it didn't have access to any of the variables and was not called.

Android "App Not Installed" using Cordova

Okay, so there's a billion reasons why this might occur...

In my case, I managed to fix it by:

Checking the version of the phone [Settings->About Phone->Android Version] - mine was 5.1.1 i.e. Android Lollipop

Googling which SDKs were valid:

Codename	Version	API level/NDK release
Marshmallow	6.0	API level 23
Lollipop	5.1	API level 22
Lollipop	5.0	API level 21
KitKat	4.4 - 4.4.4	API level 19

So I'm shooting for API 22... 

Changing the app\config.xml

Also updated the version:
