Hi

Hope it will help you.

Pls reward pts if help.

Data elements are dictionary objects that are assigned with the domains.

uses:'

• data elements are used to create relation between tables.

• data elements are used to transfer the data from one R/3 to another R/3.

• to create search helps.

Data Elements

Data elements in the ABAP Dictionary describe individual fields. They are the smallest indivisible units of the complex types described below, and are used to specify the types of columns in the database. Data elements can be elementary types or reference types.

· Elementary Types

Elementary types are part of the dual-level domain concept for fields in the ABAP Dictionary. The elementary type has semantic attributes, such as texts, value tables, and documentation, and has a data type. There are two different ways to specify a data type:

¡ By directly assigning an ABAP Dictionary type.

You can assign a predefined ABAP Dictionary type and a number of characters to an elementary type. The ABAP Dictionary has considerably more predefined types than the ABAP programming language. The number of characters here is not the field length in bytes, but the number of valid characters excluding formatting characters. The data types are different because the predefined data types in the ABAP Dictionary have to be compatible with the external data types of the database tables supported by the SAP Web AS ABAP.

When you refer to data types from the ABAP Dictionary in an ABAP program, the predefined Dictionary types are converted to ABAP types as follows:

Dictionary type

Maximum length n

ABAP type

DEC

Calculation/amount field

1-31, 1-17 in tables

P((n+1)/2)

INT1

INT4

256-max

CLNT

C(3)

LANG

Language

internal 1, external 2

C(1)

("max" in LCHR and LRAW is the value of a preceding INT2 field. The "internal" length of a LANG field is in the Dictionary, the "external" length refers to the display on the screen.

¡ Assigning a domain

The technical attributes are inherited from a domain. Domains are standalone Repository objects in the ABAP Dictionary. They can specify the technical attributes of a data element. One domain can be used by any number of data elements. When you create a domain, you must specify a Dictionary data type (see above table) and the number of characters.

· Reference Types

Reference types describe single fields that can contain references to global classes and interfaces from the ABAP class library.

In an ABAP program, you can use the TYPE addition to refer directly to a data element. The predefined Dictionary data types of the domain are then converted into the corresponding ABAP types.

If you define a local data type in a program by referring to a data element as follows:

TYPES dtype TYPE data_element.

the semantic attributes of the data element are inherited and will be used, for example, when you display a data object with type dtype on the screen. Since all data types in the ABAP Dictionary are based on data elements, they all contain the corresponding semantic attributes.

hi saurabh,

A data element describes either an elementary type or a reference type.

An elementary type is defined by the built-in data type, length and possibly the number of decimal places. These type attributes can either be defined directly in the data element or copied from a domain.

A reference type defines the types of reference variables in ABAP programs.

Hi Vasavi,

There is a blog on how to carry out planning to WBS using Excel. Please have look into it and hoping it helps you.

For On-Premise:

https://blogs.sap.com/2008/02/25/wbs-integrated-excel-planning/

You can check on implementing Commercial Project management, which also support planning via excel.

On Cloud:

I'm not sure of any app that support such planning.

Professional service on cloud (using CPM in Background) is available in case you are looking for service based company.
