Relation between Asset table

Hi Guys,

I'm working in a new assignment over assets and I can find a lot of info about the table use but I need to know how they are related as well. Could some of you help me with this? The idea of the process is recreate the asset process outside SAP. From the purchase order until the write off of the asset.

The list of table is huge but the principal are:

ANLA - Asset Master Record Segment

ANLB - Depreciation terms

ANLC - Asset Value Fields

ANEK - Document Header Asset Posting

ANEP - Asset Line Items

ANKT - Asset classes: Description

ANLH - Main asset number

ANAT - Asset type text

ANEV - Asset downpymt settlement

ANKA - Asset Classes: General Data          

ANKP - Asset Classes: Fld Cont Dpndnt on Chart of Depreciation

ANKV - Asset Classes: Insurance Types       

ANLT - Asset Texts                          

ANLU - Asset Master Record User Fields      

ANLW Insurable Values (Year Dependent)    

ANLX Asset Master Record Segment          

ANLZ Time Dependent Asset Allocations     

ANAR Asset Types                          

ANAT Asset Type Text                      

ANKB Asset Class: Depreciation Area       

ANLP Asset Periodic Values

I may be missing some table from the list please don't hesitate to name it if necessary.

Cheers,
