[Part 5 | BSP / HowTo: Exploring BSP Development and the MiniWAS 6.20 Part 5] – Conclusions As you’ve seen Part 1 (BSP / HowTo: Exploring BSP Development and the MiniWAS 6.20) gave us the foundation for holding all of our data and even a very simple entry into our category list. Now as we move into Part 2 we will discuss how to handle and display that data. 
So not to delay the process too much longer here let’s get right down to making our Class. 0.1. 0.2. Step 1: create a new class under ZCSC_FAQ called ZCSC_CL_FAQ 0.3. Step 2: create the inital 4 methods. 0.1. 0.2. GET_CAT_NAME 0.3. GET_FAQ_DATA 0.4. GET_NEXT_DATA_ID 0.5. GET_SDN_WEBLOG_BY_URL 
0.1. 0.2. Step 3: Set the parameters for our methods. GET_CAT_NAME 
GET_FAQ_DATA 
GET_NEXT_DATA_ID 
GET_SDN_WEBLOG_BY_URL 
By the way that default value for the URL is http://weblogs.sdn.sap.com/pub/q/weblogs_rss?x-ver=1.0 which is the RSS feed for the Recent Weblogs from SDN. It is also the only default value set. For those of you who are wondering – the parameter types in the graphics don’t show completely but they are +Importing+ and +Returning+. Now you have your Class, methods and parameters. Let’s get the coding in place. method GET_CAT_NAME . SELECT NAME FROM ZFAQ_CAT INTO value WHERE ID = id. ENDSELECT.endmethod. method GET_FAQ_DATA . select * from ZFAQ_DATA into table DATA.endmethod. method GET_NEXT_DATA_ID . select max( ID ) into value from ZFAQ_DATA. value = value + 1.endmethod. Now some may look at this DATA_ID code and think why did he do it this way not using intervals or something like that. Well no real good reason other than pure choice. Who knows maybe I’ll change this method after we get to the advanced features??

The CAST operation (f1!=f2, MOVE f2 ?TO f1) is currently only supported for object references.
I hav plenty of ABAP experience but I can not figure out how to resolve this issue. Any leads I can use to solve this issue?
Thanks, Tiest
Did you define m_row_def in the attributes with the proper table type?
By the way, can you also let me know how I can reward you points so everyone gets what he/she ‘deserves.’ Tiest
Points you’ll have to contact SDN and ask about that, as far as I know you can only give points if you start a message and ask a question.
Was this error ever resolved. I finally got my system patched up to 47 – it appears the previous hanging at SP38 was due to the database being full. After extending it all was well!!

When it says ‘create a new attribute called M_ROW_REF and make that of TYPE ZFAQ_DATA ‘, make sure the TYPING is set to ‘Type Ref To’ instead of the default value. (Make sure you check the attribute M_ROW_REF in both iterators).
That fixed my compile error.
I’m a total beginner to ABAP , and I’m trying to implement this tutorial on our 6.20 system. However i’m stranded on some syntax erros
Class ZCSC_CL_FAQ, Method GET_FAQ_DATA (Row 4)
The work area (or internal table) “DATA is not flat, or contains reference or internal tables as components.
and
Class ZCSC_CL_FAQ, Method GET_SDN_WEBLOG_BY_URL (ROW 67)
The lin type of table “BLOGS” is not compatible with field symbol
any idea on how to get past those ?
I’m also facing getting the Cast operatin error on the Iterator.
My system is usin kernel 1773 and BASIS SP47
Best Regards sigurdur
Please check the Attribute tab define the variable ‘M_ROW_REF’ with Typing ‘Type Ref To’.
Njoy ABAPing.

Deva.
