Change ABAP code in FM

Former Member — Tue, 02 Jun 2020 08:09:28 GMT

Hi.

I have a custom field in table BKPF.

When i am trying to change value in this field (TC: FB02) i have a problem.

Value in this new field is not changing but change log on document is created.

I have found FM CHANGE_DOCUMENT which should make changes in table BKPF.

Include LFAGL_F005F03.

I whant to add new line to code of this FM (with my new fileld) but how to do this without entering acces Key?

There is no enhance point...

Code:

...

UPDATE bkpf
SET aedat = bkpf-aedat
upddt = bkpf-upddt
xblnr = bkpf-xblnr
bktxt = bkpf-bktxt
stodt = bkpf-stodt
xstov = bkpf-xstov
duefl = bkpf-duefl
brnch = bkpf-brnch
numpg = bkpf-numpg
xref1_hd = bkpf-xref1_hd "Note 624215
xref2_hd = bkpf-xref2_hd "Note 624215
WHERE bukrs = bkpf-bukrs
AND gjahr = bkpf-gjahr
AND belnr = bkpf-belnr.

...

Thanks in advance

Hello tomasz.piwowarski

It's a standard SAP function, only SAP is allowed to change it by default. Modifying standard objects is almost always a last resort. Try looking for other ways of achieving your goal.

For example, you could try to implement a BTE for this transaction, as it is described in this answer: https://answers.sap.com/comments/6621494/view.html

Kind regards,
Mateusz

Hi Tomek,

Did you have a chance to go through following article?

Yes. When i am posting new document everything is ok.

Problem is in FB02 in change mode.

Part of this article

"Note: New Z fields can be added to FB03 only in the form of hard screen modification and is not recommended."

I add this field to FB02 FB03 screen.

Now i am looking for solution to make a posibility to change value in this field.

Please use a meaningful title (like "update custom field in FB02" for instance).

Please use the CODE button to format your code so that it's shown in a more user-friendly format (colorized).

While modifying standard is a last resort, it's better than making a copy of the standard and changing that. If you have to change the standard, then do so, but make sure it is really clear that this is a modification and why it's necessary.

During upgrade, when you run SPAU, the modification will be visible and will need to be re-applied.

I will add that my experience of many SAP implementations is that every single one has had a modification to standard somewhere.

Hello Matthew

Agreed, there is always an exception to the rule. That's why I said that it's the last resort. Not, that it's not possible or shouldn't be done at all.

And who says anything about copying? 🙂 Definitely avoid copying of programming objects, if possible.

Kind regards,

Mateusz

Nobody said anything about copying. I was more advising the OP than replying to your answer.
