Rules Assignment for Sybase Tables

Hi experts,

I have replicated a table "gg_color1" from sybase to HANA successfully. I can see data in HANA Studio.

Now I want to add a field "CHANGE_DATE" to the target table and give it the value SYSDATE.

First, I add table in  Table Settings in LTRS. I can find the table "gg_color1" in the list,

But when I click YES, it popups a message showing the table not exists in the source system.

Anyway , I click Yes and the table is added with its table structure. I add a new field CHANGE_DATE. Then I want to create a new event-based rule to assign value to it. But it shows ABAP code contains syntax errors.

I check the syntax and it shows:

then I find that the table "gg_color" does not exist in HANA DB any longer. It seems to be deleted.

I use the same way as I deal with ECC tables, but it doesn't work anyway.

So what's the process to create a rule to assign value to a new added field for a sybase table?

Thank you for your any input!

Regards,

Chong
