Solved: Why am I getting overwriting of a protected field ...

kirpi · ‎2023 Jan 12

Hello all,

I'm new to abap and to this community. Wish I can be useful here in the future, after I get some experience on abap.
I wish to ask you a question regarding my simple project which should be pretty basic. But this is not the case at all right now. I keep getting this error on one end of the program whenever I double click etc. I know that this should be about pai but I dont have a pai! But on the other end I dont get this error. The ends are almost similar and I cant find much of a difference. Would someone please help me out here? Many thanks for reading.

Check the declaration of your internal table named: gt_imported - make sure that:

a. it contains a field named SELKZ ;

b. it is not seen as read-only by the code that calls fm REUSE_ALV_GRID_DISPLAY (it might be treated as read-only if passed as an IMPORTING parameter into a class method for example).

Please clarify the question. What do you double click? Any screenshot? What EXACT error message do you get? What is the corresponding ABAP code? Etc.

Of course, I'll do my best on answering. Please excuse me for sending such a late response as it was the evening time in here. Also keep in mind that I'm a total noob in abap so don't judge me 🙂 There are some explanations on the pictures as well.

When I click on the first option and run, alv comes up to the screen and its totally normal.

main.png

I double click on the alv on second option, on any cell of any column and I get the dump screen like the following.

dump.png

The first and second parts of the code are divided with includes, I copied and pasted all. There may be some redundant lines or blocks as I have been trying everything out for the code to work. Please don't mind them.

My question once again is, how can I get rid of the dump screen when I do anything at all, on the second screen? Thank you kindly.

Let me know if there's anything missing.

IMPORTING parameter of method or function module, as people often use the old way

I appreciate your answer, thanks a lot. Update: it works fine now.

Sandra_Rossi · ‎2023 Jan 13

It's best to embed the images to have text and images at the same place, like this (all the text and images below are yours):

When I click on the first option and run, alv comes up to the screen and its totally normal.

I double click on the alv on second option, on any cell of any column and I get the dump screen like the following.

The first and second parts of the code are divided with includes, I copied and pasted all. There may be some redundant lines or blocks as I have been trying everything out for the code to work. Please don't mind them.

My question once again is, how can I get rid of the dump screen when I do anything at all, on the second screen? Thank you kindly.

kirpi · ‎2023 Jan 17

I will close the topic if your help can solve my problem but I couldn't try it yet because of other office work. I appreciate your answer, thanks a lot. I will let you know if there is anything else about my problem.

Kind regards.

kirpi · ‎2023 Jan 17

Thank you so much, the problem was in selkz as you suggested.
