ALV Hierarchical Container

[alexandre_docarmorocha]

Dear experts!

How we might have two ALV hierarchical on the same screen?

I could not find any solution in a regular basis.. as using Docking or CL_SALV* or CL_ALV*.

The only way to have a hierarchical ALV is using REUSEHIERARCALV function or SALV class using Factory, but I could not find out how to have two ALV Hierarchical at the same screen.

Any tips or suggestions?

Best regards,

Alex

Hi Alex,

To have 2 ALV hierarchies, you'll have to use control framework. One dynpro with 2 custom containers inside, or one dynpro with 1 custom container + one docking container. There are a few other possibilities.

The root class to use is CL_GUI_ALV_TREE (which wraps the control CL_GUI_COLUMN_TREE by the way), which is also wrapped by CL_SALV_TREE.

As SALV is to be a simplified version of ALV, so I would recommend CL_SALV_TREE by default, but I don't have experience with it. See demo programs SALV_DEMO_TREE*.

If you're not comfortable with control framework, see DWDM transaction which provides examples. For 2 controls in the same screen, see for instance SAP_PICTURE_DEMO.

Hi Sandra,

The CL_SALV_TREE is different than cl_salv_hierseq_table( see this demo SALV_DEMO_HIERSEQ_SIMPLE ).

Using Hierarchical stuff we would have two different levels( header and Item) what the ALV tree does not allow.

The SALV_HIERSEQ has the method cl_salv_hierseq_table=>factory that does not have container paramenter, there is not way to use it in a container.

The other classes as cl_salv_table/CL_SALV_TREE have the method "factory" with the import parameter "container_name" what permit us to use the container object thus use the control framework.

Got it?

Any idea how to achieve it?

Yup, sorry, I made a confusion between ALV hierarchy and ALV tree. My answer was only about ALV tree.

About ALV hierarchical-sequential, I only know the ABAP List version (the class wrappers still use it), there's no control for it.

So, there's no solution. The workarounds I see is either to use block lists (lists are written one below the other), or use full screen on 2 external modes using IMC and switch between the 2 modes using a button to make things smoother to the user (see RSIMCTST program). Be careful with IMC, I don't think whether there is support from SAP, nor if it will be maintained.
