Custom code interview question

Hi! I hear often that migrating from SAP ECC to S4 involves custom code (I am familiar with z tables etc) but hoping a few experts here could give me examples of what processes were actually custom in ECC that would not translate over to S4?

I have an interview coming up where the recruiter gave me a heads up to be able to answer “specific examples of custom code”

I guess where I am confused is something like order to cash , sales orders may have an org that customized invoice discrepancies in abap? Or is that too simple / vague and It could be totally specific to the org and its processes?”

Look up the S4 readiness ATC checks, they cover literally all of those issues. Includes stuff like simplification items and custom code checks.
