j1inpp - Update business place for FI document

hi.

We have scenario, where we have MM document created with MIRO in which Business place(BUPLA) and Section code (SECCO) is entered . And for corresponding FI document gets generated without Business place in tax line iteam due to the previous config.

There is standard t code j1inpp which updates BUPLA and SECCO for MM related document number generated from MIRO and its respective FI documents,

case : As i have debugged the code,this report work only when MM document is without BUPLA and SECCO and updates corresponding documents.

Is there any other standard transaction to run such kind of scenario,

Can i update the same by making Zreport by copying the standard code and making changes in the code which i have tried and works fine?

Regards,
