Difference between the design of clusters PCLx and others like RFBLG etc .

324 Views

There are a few nagging questions which I was not able to find in the forum hence i have to post a new question.

I am a little confused about the difference between the different clusters .

If i start with RFBLG i.e. the cluster for BSEG BSEC etc ,I can see that the tables which are part of this cluster

can be viewed through different methods like

1) whr usd list for RFBLG

2) dd02l table and give the required parameters there

now when I compare this with another so-called cluster PCL1 if find that PCL1 is not recognized as a cluster

and also I am not able to see the same in dd02l table when i give PCL1 and the tabtype as cluster which I was able to see

for the RFBLG ,there are other tables similar to RFBLG .

1) SO what is the difference between the RFBLG type of clusters and the PCLx type of cluster

2) are pclx and rfblg..type of clusters same ?

3) why does PCL1 shows that it is a transparent table ? where as rfblg shows in a diff way in se11

4) i know we access data from PCL1 using import and export stmts ,DO OR CAN WE DO THE SAME FOR RFBLG

5) I found that each and evry cluster table had diff fields ,this was kinda surprising for me as I had been thinking

that all cluster tables need to follow a certain rule ,SO WHO DECIDES THE FIELDS OF A TABLE CLUSTER ?

6) PCL1 has the index button enabled ,which again I think is not according to the cluster table rules?how?

7) I understand that we can save data in form of internal tables in the PCL1 cluster ,can we do the same in RFBLG ?

8) Can I think on lines that PCL1 and RFBLG type of cluster are two totally different types of data dictionary objects

and the usage and implementation of both of them is different and that the design and the BASE of both of such objects

is different .

I know this is a long list but I am sure that answers to these questions would really require some one who has really really work hard and invested a lot of time in understanding the dictionary system.I am awaiting a few answers ,few hints and a healthy discussion till we get them .

Thanks ...
