i want to collapse lines in matrix. In the form 65 in SAP, i see it was possible but i don't find the way to do that.
(I search in this forum and in the SDK's help)
With grid, it was possible but i can link column to an object type. and in matrix i can link column to object type but i can't collapse lines.
Are there someone who have doing the same thing (collapse lines), can you give some codes to do that ?
Thanks for your response.
