ABAP code to compare 7.40 inline data declaration with original syntax

The below ABAP code uses the older none in-line data declarations. This allows you to see the coding differences/benefits of the later inline syntax. It may also be useful if you are using an older version of SAP as some of the newer syntax above, such as the @DATA is not available until 4.70 EHP 8.

DATA:

ld_es_root_category
 
 TYPE COMT_CATEGORY ,
ld_iv_hierarchy_guid
 
 TYPE COMT_HIERARCHY_GUID ,
ld_et_root_categories
 
 TYPE COMT_CATEGORY_TAB .


ld_iv_hierarchy_guid = 'Check type of data required'.
