Trading Partner in FAGLFLEXT is missing

Dear all,

We activate trading partner and set up the trading partner into customer master and vendor master.

As a result of this setting, system is posting accounting item with trading partner such as Sales and COGS. (We can see the code in Table: BSEG.)

However, we found the value of tranding partner (RASSC) in FAGLFLEXT is BLANK.

Do you know the reason and how to solve this?

If you have any idea your information would be greatly appreciated.

Thanks and Best Regards,

Satoe
