View creation and populating key figure to datasource appended field

Question

Hi
the data we want is like in 4 tables
J_3GVERSI  +  EQUZ + ILOA+ ANLC
HOW should i create a view on these four tables .
j_3gversi _ equnr
equz - equnr, iloan
iloa- iloan(key), comp code,asset no,asset subno
anlc- comp code asset no asset sub no
my two key figure values are in J_3gversi , and 1 more keyfigure i will append it to my datasource on this view and the value for this  will be obtained if i give 5 field values( from ANLC(table), compcode,asset no ,asset subnumbr, fiscal year and depreciatio area in where condition for select statement in cmod .)
to give these 5 values in the where condition in my cmod code for my datasource I tried to make this view.
i have linked
j_3gversi  with equz - using equnr
equz with iloa- using ILOAN ( since my asset no and asset sub number in this table is linked to equipment number  using ILOAN field)
ILOA with ANLC- using ( company code, asset number and asset subnumber)
though the field names are different for my asset number and subnumber in both the tables , they have same data element(component) -
IS it fine to join two tables with fields having different field names but same component.
asset number field name is  in ILOA-anlnr and ANLC-anln1 though component type is same - anln1 for both
similarly asset subnumber has like  ILOA- anlun and ANLC- anln2 with same component type-anln2
now in cmod for the function module i am writing select statement like this
code in cmod for transaction data
when mydatasource
loop c_t_data into lv_ctdata3
1.     SELECT SINGLE * FROM anlc WHERE bukrs EQ lv_data3-bukrs AND 
2.                                     anln1 EQ LV_DATA3-anln1 AND 
3.                                     anln2 EQ LV_DATA3-anln2 AND 
4.                                     gjahr EQ Lv_data-gjahr AND 
5.                                     afabe EQ  '01 ' . 
6.     IF SY-SUBRC EQ  0 . 
7.       CALL FUNCTION  'FI_AA_VALUES_CALCULATE' 
8.         EXPORTING 
9.           i_anlc = anlc 
10.         IMPORTING 
11.           e_anlcv = l_anlcv. 
12.     ENDIF. 
lv_data3-nbw =l_anlcv-nbw.
modify c_t_dat from lv_data3
end loop

Hi ,
IS it fine to join two tables with fields having different field names but same component.
1.Yes we do this many times .We combine fields having different names but functionally they are the key values to match .
No issue with that untill they are in same format and you want to match data based on those fields .
HOW should i create a view on these four tables .
2.For view you can create view on 2-3 tables with matching fields and for complex logic you can populate additional fields via CMOD code .
