Hierarchy using a flat file for a master data load.

Question

Can anyone please tell me the steps involved in creating a hierarchy in BI 7.0.  and loading the data using a flat file into the created hierarchy? I have seen some posts and weblogs but they were not helpful and i have been getting some errors which i dont know how to resolve.
Can someone please give a clear steps and procedure for this?
Thanks a lot in advance.

Hi,
The flat file is generated in application server by executing an ABAP program in SE38.
This ABAP program contains the logic to generate hierarchy.
In our case we used a DSO to store employee & supervisors.
This program generated a flat file in tmp folder in application server
In our case, To load this flat file we  created an Infosource on our master data using direct update using RSA1old Tcode
after Infosource is created right click on the InfoSource and click on Assign DataSource.
Give the Source System name
When you open this Info source you can select data source as YHIEROBJ_HIER and then activate the InfoSource.
create an Info Package to load the Hierarchy. Right click on the PC Files (Source System) and click on u201CCreate InfoPackage".
Under Extraction tab give the flat file name which is generated by the ABAP program in AL11.
Select the hierarchy which you want to load. Also, you can rename the Hierarchy after loading it. The update method is selected as u201CFull Updateu201D.
Logic for Generation of flat file & ABAP Program:
Flat file structure:
Node ID     InfoObject     NodeName     Parent ID     Date To      Date From     Language
u2022     u201CNode IDu201D indicates the unique number which defines the Node.
u2022     u201CInfoObject u201Cgives the name of the InfoObject which is assigned to this Node ID.
u2022     u201CNodeNameu201D is the name you specify to that Node.
u2022     u201CParent IDu201D is the Node ID to which the Current Node ID reports to.
u2022     u201CDate Tou201D and u201CDate Fromu201D are taken for time references (You can set them constant).
u2022      u201CLanguageu201C is set to English (E).
The program Logic can be :
Declare the hierarchy structure
Get the data from DSO into internal table
Read all the EMP values into NodeName Field of the table
Build lookup table for Parent Node ID
Fill Parent Node ID field
Append this data to work area & then to another internal table
You need to declare the selection parameter as SSFILE1
& use following code to write back the file
  OPEN DATASET SSFILE1 FOR OUTPUT IN TEXT MODE ENCODING DEFAULT
     MESSAGE MSG.
  IF SY-SUBRC NE 0.
    MESSAGE E008(ZBW1) WITH MSG.
  ENDIF
Populate the output from that internal table into final work area.
Transfer this final work area to the ssfile1 which is the desired output file.
and   CLOSE DATASET SSFILE1.
When this program is executed, selection screen asks for the name of file
Enter the desired file name & execute
flat file would be generated in the Application server now.
To view the File, Go to Transaction AL11. Search the directory /tmp. Double click on this directory.
This opens the list of flat files under this directory. Double click on the file name.
Hope this helps.
Thanks,
Rashmi.
