Please use the buttons "..." and "</>" to make the code easy to read. See here the detailed steps: https://community.sap.com/t5/questions-about-sap-websites/how-to-post-code-in-sap-community-gt-2024/...

[Sandra_Rossi]

Note that you're using outdated code, don't declare global variables, don't use TABLES. Instead, use inline declarations, constructor expressions and so on. Don't transfer the constant "SY-REPID" into an intermediate variable, use it directly without intermediate.

Hi rnegi,

Please make sure your workarea WA_TOP1 and internal table IT_TOP1 are defined with correct type.
DATA:
wa_top1 TYPE slis_listheader,
it_top1 TYPE TABLE OF slis_listheader.
Thank you!

[Sandra_Rossi · Accepted solution]

I'm nitpicking: I guess that REUSE_ALV_COMMENTARY_WRITE has parameter IT_LIST_COMMENTARY of type SLIS_T_LISTHEADER, so I would fix it by keeping IT_TOP1 typed like SLIS_T_LISTHEADER.

DATA wa_top1 TYPE LINE OF slis_t_listheader.
DATA it_top1 TYPE slis_t_listheader.

[rnegi · Accepted solution]

thanks!

[raymond_giuseppi]

You declared 

it_top1 TYPE TABLE OF slis_t_listheader,

So it_top1 is a table of tables of records of structure slis_listheader (slis_t_listheader is already a table type definition)
