For the Baan standard session tfgld1401m001 we have added a customized
report. When we login with a user attached to english language (2) the
customised report can be printed.
But if we login with a user attached to simplified chinese language (o)
then this report is not visible. i.e. when we go to standard reports
session (ttadv3530m000) the customised report is not listed."

We are using SSA LN6.1, SP1, Oracle9i

I am not familiar with LN but, on IVc4, the reports are language dependent, so that a report build build based on language 2 (English) needed to be copied (linked to object of language 2) to the other languages. Check if this applies.

Yes this functionality was available in version C4/ERP but not in SSA LN so that's why I am wondering what is the solution for this issue
