Thanks Raymond.
We have many custom fields that need to be put into the custom tab and worry they cannot fit into the screen. So I am considering to put some custom fields into the second tab.
May I ask you whether I can put an alv grid/ table into the first custom tab? we have a custom table with multiple records per cost centre and want to show/ edit them in the cost centre master's custom tab. Is it possible?
Thank you very much!
Sunny
