Hi!
I try to enhance standard component /SAPSRM/WDC_AOFC_BEV with new component usage (say, SALV_WD_TABLE). It allows me to add new usage, but the usage does not appear in the "Component Usages" tree node.
Is it a bug? Is it possible to enhance a standard component with new component usage?

Thanks Thomas.
We'll try to enter the support ticket.

I've never tired it myself, but the online help does list that you should be able to use the enhancement framework to add new component usages:

Based upon this help document, this might be a bug. You might very well have to enter a support ticket.

Hi Thomas!
We've been communicating with SAP on this issue for a while and last response we obtained is next:
Dear customer,
the possibility to create external controller usages (as required for
the ALV-usage) is not supported by the Web Dynpro ABAP development
tools. However, you could try a programmatic apporach by adding the
ALV-usage dynamically (e.g. in methods or method exits created within
your enhancement implementation).
See test component WDR_TEST_DYN_ALV_USAGE for details.
What's your opinion on this? Is it really not a bug?

I don't know what the details around the support message were. I can only point you back to the on-line help statement that this enhancement option is supported. It sounds like you can add the component usage with the enhancement framework, but can't do the reverse mapping. This might be the aspect that isn't supported.
The workaround of doing the component usage or even just the data binding in coding does seem like a doable workaround.
