Parent and child relationship using OOPS

Former Member — Wed, 12 Feb 2014 12:04:34 GMT

Hello experts,

I have to create a tree that displays parents with its childrens. I have code from which i have created a tree but next what i want to do is achieve relationship as

Product_1
- Child A
- Child B
Product_2

I have attached code and screen shot of table below if anybody have idea regarding this issue please share it with me.

form create_hierarchy .

data: lt_products type table of /nyh/ap_products,

ls_products type /nyh/ap_products,

lr_product type ref to /nyh/cl_ap_product,

lt_versions type /nyh/ap_t_version,

ls_versions type /nyh/ap_s_version,

lr_version type ref to /nyh/cl_ap_version,

* lt_versions type table of /nyh/versions,

ls_version type /nyh/ap_versions,

lt_packages type table of /nyh/ap_packages,

ls_packages type /nyh/ap_packages,

ls_tree type /nyh/ap_s_tree_data,

l_version type c length 8.

data: l_top_key type lvc_nkey,

l_product_key type lvc_nkey,

l_version_key type lvc_nkey,

l_last_key type lvc_nkey.

* Add one Generic node at the top

ls_tree-node_type = c_node_top.

perform add_node using 'Applicon Products'

ls_tree

changing l_top_key.

select *

from /nyh/ap_products

into table lt_products.

loop at lt_products into ls_products.

clear: ls_tree, lt_versions, ls_versions, lt_packages, ls_packages.

create object lr_product

exporting

i_product = ls_products-product

exceptions

product_not_found = 1

others = 2.

if sy-subrc <> 0.

continue.

endif.

move-corresponding ls_products to ls_tree.

ls_tree-node_type = c_node_product.

perform add_node using ls_products-product

ls_tree

l_top_key

changing l_product_key.

call method lr_product->get_versions

receiving

et_versions = lt_versions

exceptions

no_versions_found = 1

others = 2.

if sy-subrc <> 0.

continue.

endif.

loop at lt_versions into ls_versions.

clear: l_version, ls_tree.

ls_version = ls_versions-r_version->get_version( ).

move-corresponding ls_version to ls_tree.

ls_tree-node_type = c_node_version.

call function 'CONVERSION_EXIT_ZVERS_OUTPUT'

exporting

input = ls_version-version

importing

output = l_version.

perform add_node using l_version

ls_tree

l_product_key

changing l_version_key.

lt_packages = ls_versions-r_version->get_packages( ).

loop at lt_packages into ls_packages.

clear: ls_tree.

move-corresponding ls_products to ls_tree.

move-corresponding ls_versions to ls_tree.

move-corresponding ls_packages to ls_tree.

ls_tree-node_type = c_node_package.

perform add_leaf using ls_tree

l_version_key

changing l_last_key.

endloop.

call method gr_alv_tree->expand_node

exporting

i_node_key = l_top_key.

endform. " CREATE_HIERARCHY
