Hello,

Try regenerating your TMG & check in SM30 again! Have you defined a single-step or a double-step maintenance for the table?

How many fields does your table has..? Secondly click on screen layout and check what fields are displayed there..

You don't have any key fields other than MANDT 😮 ??

How do you think that the system will identify the unique records in the table? I am suprised ABAP compiler doesn't give an error when activating the table

Hi

That's the problem

You have defined a table without keys, it's not enough to use MANDT as only key field: you needs to insert other fields as key, at least another one.

Which information u need to insert in your table?

There is no need another key field. Because table contain 2 fields , matnr and menge. They could be more than once.

is it mandatory defining another key field.

Hello,

I think you are not aware of basic RDBMS concepts.

MANDT is used for client-dependent tables & it's value is same (in the same client). Table Keys are used to identify unique reocrds in the table, in your case you'll have only one record. Hope you get the point.
