How to access columns of ALV(in Component B) through Component A?

[preethi_santhanam]

Hi,

I have 2 Web Dynpro Components; 'Component A' and 'Component B'.Component A has a WD application.

Component A has a component usage of Component B. Component B has an ALV component usage.

How can I add a new column to the ALV of Component B from Component A?

Thanks & Best regards,

Preethi.

You can place the component usage of the ALV into a pulibc attibute of the component controller of Component B or pass it back as a returning/exporting parameter of an interface method in Component B's controller. Either way Component A can get access to the ALV usage object without having to actually declare a component usage.

Hi Thomas,

Thanks for your reply. Component A has ViewA which just contains a View Container. Component B has ViewB which fits into this View Container via Component Usage. This ViewB has an ALV usage. I need to make changes to this ALV columns.

Unfortunately, Component B, is a standard component (FKK_WDY_DMS) and the attributes are not public. Any other views?

Thanks & Regards,

Preethi.
