I can send out Global segment from company MA to other company (like AFTSCH) successfully. I try to update the account name in company MA then. It can update the table erp.GlbCOASegValues but not erp.COASegValues of target company.
Anythings I miss to setup.
I check that I miss to enable Global Table Maintenance in both Companies. After doing that, the supplier information can update in target company.
Thank you hasokeric to help me solve the problem.
