Thanks Jacek, it is working.

Can i know, what is the 1320 referring here. How can we determine this number?

Thanks in advance,

It’s a command ID.

Open SalesTable form (for example) in AOT and navigate to Design > ActionPabeHeader > SalesOrder > ShowGroup. You’ll find two command buttons there, HeaderViewButton and LineViewButton.

Open properties of HeaderViewButton and place the cursor to the value of its Command property. You’ll see “Header view: 1320 (i.e. command name and ID).
