Program crash when scrolling ALV table

Hello, I am learning ABAP and for a few days, Im stuck in a problem of program crash when scrolling through ALV table. Everything worked perfectly when I used REUSE_ALV_GRID_DISPLAY and for field catalog SLIS_FIELDCAT_ALV. But then I had to switch to CL_GUI_ALV_GRID and LVC_S_LAYO with related changes. After that, scrolling crash problem appeared. No big data, just normal IDs, names etc. and max amount of results should be 513 rows and 3 columns. Interesting thing is, the more columns i add, the earlier i get the crash in scrolling. Dump text is "Field symbol has not been assigned yet."

Did someone faced similar issue and how did you fixed this? 😞 Thank you

This is ALV part of the code. Filling of the table etc. is right above this:

Crash when scrolling ALV makes me immediately think that you have passed a LOCAL internal table to the ALV:

CALL METHOD lo_alv->SET_TABLE_FOR_FIRST_DISPLAY
  EXPORTING
    is_layout = ls_layout
  CHANGING
    it_outtab = lt_crmd_orderadm_h
...

i.e. the argument of IT_OUTTAB should not be a local internal table.

Only global variables or public attributes of alive instances can work with ALV (especially when scrolling but for other features too).

Please edit your question (Actions>Edit), select your code and press the button [CODE], which makes the code appear colored/indented, it'll be easier for people to look at it. Thanks!

Or perhaps a field name on the field cat is different from the table.
