Invalid extract structure template &2 of datasource &1

Question

Hi all,
I really need help in this one. I am trying to create a generic datasource and it gave me this error. I did little research and found that my key figures are pointing to the currency or unit which is in an include. and one of the note says that the currency and unit has to be in your field list. I am using notes 335342 and 202162.
I am copying a part which I am not able to understand since I am doing this for the first time so Please help.
"If the currency or the unit a key figure refers to is not located in a table but in a structure, the key figure has to be removed from the view and read via a customer exit (see below). Structures cannot be included in a view.
ATTENTION!! Often the key of the table in which the referenced unit is located, does not agree with the key in the table with the corresponding key figure. In this case, the join condition of both tables is not unique in the view definition, that means for each key line of the table with the key figure, several lines of the table with the unit may be read: the result is a multiplying of the number of lines in the view by a factor corresponding to the number of lines that fit the key figure, in the unit table. To be able to deliver consistent data to a BW system, check whether the unit of the key figure in question should always have a fixed value. If yes then you can determine that in the view definition via 'GoTo -> Selection conditions'. If no, then you must proceed as follows:
a) Remove the key figure from the view
b) Define the DataSource
c) Enhance the extract structure by key figure and unit for each append (Transaction RSA6)
d) Add the key figure and the unit in a customer exit
2. A view is already used for the extraction.
Thanks for all the help in advance.

Hi AHP,
It beats me as to how can I add those fileds from FAGL table in the view, I am just not getting it. Or is there any other table that I can add these views.Some times it gives me this error "Field TCURC-RTCUR does not exist in any of the base tables." or similar to that I dont know what does that mean, Can you let me know plz?
Also all the links that you have given are really great, I will doing the FM for first time so it took me time to sink in the process and concept. I am trying to use one of the code that Dinesh has given in one of that posts and just adding my table names in his tables just as starting point. I am not getting what exactly do I have to do in these two sections can you help me understand.
cursor
S_CURSOR TYPE CURSOR.
Select ranges
RANGES: L_R_ZYEAR FOR YSALES-ZYEAR,
L_R_ZMONTH FOR YSALES-ZMONTH.
why exactly is it zyear and zmonth can we change it? what criteria?
OPEN CURSOR WITH HOLD S_CURSOR FOR
SELECT (S_S_IF-T_FIELDS)
FROM YSALES .
select BUKRS
ZYEAR
ZMONTH
WERKS
MATNR
SLSCAT
KNDNR
SPART
MATKL
MENGE
DMBTR
VV702
VV703
VVADS
VV704
VV731
INTO CORRESPONDING FIELDS OF TABLE I_YSALES
FROM YSALES
WHERE ZYEAR IN L_R_ZYEAR
AND ZMONTH IN L_R_ZMONTH.
WHERE MATNR IN L_R_MATNR.
WHERE WERKS = WERKS
AND MATNR = MATNR
AND KNDNR = KNDNR
AND SPART = SPART.
IF SY-SUBRC = 0.
SORT I_YSALES BY WERKS MATNR .
ENDIF.
Do we have to add here all the fileds that we want from the table? and what does "WHERE KNDNR = KNDNR" means , how should i relate it to my table.??
Thanks again for all the help.
