Hello Naveen,

Every composition subnode ( like your item subnode ) has two default associations. They are "To Parent" and "To Root", since your subnode item is a subnode of the ROOT , executing either of them will get you the ROOT data. Execute a Retrieve By Association, with your item node instance keys , node as ITEM , association as "TO ROOT" or "TO PARENT" and the "IV_FILL_DATA" set to true , to collect the ROOT node data directly from the Retrieve By Association call.

Indranil.

Hello Naveen,

You can able to read the root information from the item information using io_read->retrieve_by_assocation method.

pass the exporting parameter has

it_key = item key

association = item-to_root

fill_data = abap_true

Importing

et_data ( root information )

Thanks,

Hi Naveen,

To get RooT data you have to use to_root association as in your case root is also a parent node you can use to_parent association also.

io_read->retrieve_by_assocation

exporting

it_key = lt_key " key table that hold item keys

association = item-to_root " association name (it is created by default)

fill_data = abap_true " make it to fetch data

Importing

et_data = lt_root_data

you will get your root data in lt_root_data.

Regards

Hi Naveen,

To get the root data create a Determination in item node,

in the determination do the retrieve with help of parent key

then the root value will retrieve.

Then map the root emp_id to item emp_id

then do_modify and pass item->emp_id to change fields.
