The ABAP Query comprises four components:
Queries
InfoSets
User Groups
Translation of Query
Lets look into them in detail:-
Queries
InfoSets
InfoSets are special views of data sources. An InfoSet describes which fields of a data source can be reported on in queries. An InfoSet can be assigned to several roles or user groups. Advantages–
By creating InfoSets and assigning them to roles or user groups, the system administrator determines the range of reports that the individual application departments or end-users are able to generate using the SAP Query. End-users are able to work only with those InfoSets that are relevant to their particular area, as designated by the role or user group that they are assigned to.
USER Groups
The User Groups component is used to maintain user groups (from a security standpoint). Users working in the same application are assigned to the same user group.It does not matter who actually defined a query in a user group. Every user assigned to the user group is able to execute the query. Users in a user group need to have the necessary authorizations before they are able to change or redefine a query. Every user in a system can be assigned to several user groups.
Translation/QUERY Component
A lot of texts are generated when defining queries, InfoSets, and user groups. These texts are displayed in the language that we chose when we log on to the SAP system.We can compare the text/languages using this component.
Data processing in Queries
Data can be processed and presented in 3 ways:-
BASIC LIST – Presents data in the order defined by the functional area ( supports sorting and summation ). STATISTIC – Shows the statistical figures calculated from the basic data. RANKED LIST – A ranked list is a specialization of a statistic. E.x. Top ten customers of a travel agency.
A query can have one basic list , upto nine statistics and upto nine ranked lists.
