Error 'ABAP program lines are wider than the internal table' not showing in other SAP systems

[ricky_shaw]

Hi,
I am in Dev system with latest S/4 HANA.
I am modifying an old Z* prog (before 2010) that uses ALV FM: REUSE_ALV_FIELDCATALOG_MERGE.
After my changes its dumping saying "ABAP program lines are wider than the internal table'.

I changed my ABAP editor setting by checking on 'Downwards Compatible length (72) ..etc' & is working fine.

But my other QA system (with latest S/4 HANA) where my code is NOT moved into it yet is NOT showing any dumps yet.

How is this possible?

Only you can analyze what is different. That's one of the numerous problems of using these obsolete function modules. You shouldn't have lines of more than 72 characters in your ABAP program if you use the I_TABNAME parameter. It has been discussed a lot. Hopefully, CL_SALV_TABLE has not these odd drawbacks.

It should not be difficult to find the reason because this error happens READ REPORT into an internal table whose width is too short for the read program, as explained in the ABAP documentation, so just add a breakpoint at READ REPORT and you'll get the exact reason in a matter of minutes.

just check your code to see if there is any line with too many characters

There are NOT many characters in any lines .
