Hi friends,

I am new to ABAP .Could any one pls suggest me

1) whether we have to remember the tables in all function modules and their fields.I think its difficult.Then,what should be the alternative.

2)what is the diff. between VBRK table and NAST table in SD Billing tables.

3)what is the process in real world scenarios .whether functional people give us specs abt the tables on which we have to work.Can any one give the process.

Thanks in Advance.

Hi Sagar,

Welcome to SAP.

1) You don't have to remember all those table but some of the common use table. there is the link that I use most of the time

http://www.erpgenie.com/abap/tables.htm

2) VBRK is Billing Document - Header, and NAST is the message table.

3) Typically, Func. Consultant will gather the requirement from the user and draft a functional spec for technical guy like you. You may also need to prepare technical spec based on the functional requirement. However, the criteria of functional spec and technical spec yield the same purpose; in which the outcome (result) must be meet user expectation, and present the information that required, or manipulate the operation correctly.

Hope the above helps.

Cheers,

Patrick

Hi Sagar,

You don't have to remeber as you go on working you get to know the function modules and their fields; But its good to remeber some of them which are commonly used such VBAK, VBAP, MARA, KNA1 etc.

The diff. between VBRK table is for Billing Document: Header Data and NAST table: Message Status in SD Billing tables.

As an ABAPer you will recive the FS from the project functional guy and we have understand the whole functional requirement and prepare Technical Specification Document and after getting it apporved by Functional member , develop it or may be some time, parallely you need to write coding to check functionality.
