Hi All,

I will be really grateful if someone could go through the following codes (2 different places) and tell me why in CODE 1 i am able to append rows to the Webdynpro ALV on clicking on the Append Rows button while nothing happens at all on doing the same in case of CODE 2.

This is really frustrating. Help is really appreciated.

Hi Priyank.

I do not thinks the problem is in your coding. What about the mapping? Which

mapping type do you use (reverse mapping or setting node directly via interface

controller) ? Cardinality of the node you map to the ALV? Is there any difference

beside the structure between the node you map in Code 1 and the node you map

in Code 2?

Just check this.

Cheers,

Hi Sascha,

I know i might be sounding really weird on this. But as I see it now, even the second code has stopped working. Means now I am not able to append rows in either of the cases. What i did was to create another container in the view and then put some elements in it. After the problem, i reverted back and removed the container (just to check if that was the cause of the problem) and now I find that what was initially working is not so any more.

1) I am using direct setting of node via interface controller

2) Cardinality of both nodes mapped to the ALVs are 0:N

3) Yes the structure of both nodes are different. Both nodes are based on different structures returned from different RFCs? Should this matter too much?

Any ideas?

regards,

Priyank
