Loading customer hierachy from flat file

Question

Hello Friends,
I have a requirement to load time dependent customer hierarchy, to be used in BEx reports. I have gone most of the threads in the forums about 0cust_sales and 0customer.
The table that is updated in ECC is KNVH. As we cannot map the data from KNVH directly to 0customer, I have loaded the data to 0cust_sales using using datasource 0CUST_SALES_LKDH_HIER.
Now I have downloaded the 0cust_sales hierarchy using the program Z_SAP_HIERARCHY_DOWNLOAD and changed the object there to reflect 0customer.
Once the file is downloaded, I tried to create a file datasource for 0Customer and load the file.
Initially I found issues with format, as 0cust_sales would have a combination of sales org, dist channel, division together with customer. I replaced all those numbers with zeros.
The preview looks good with all the fields properly populated.
But still not able to load the file. I have checked in SLG1, its all green. but hierarchy does not show any update.
As a second step, I tried to create a manually 2 nodes in the 0customer hierarchy and tried to download it using the program. Then tried to upload again. Its working after manual change only for some entries
Any inputs are highly appreciated.
Thanks
Ed.

Thanks Aditya for your reply.We are on BW 7.3.
These are the steps taken
1. Loaded the 0cust_sales hierarchy from ECC(knvh) - good
2. Downloaded the hierarchy as a .txt file using Z_SAP_HIERARCHY_DOWNLOAD program
3. Created a Datasource for hierarchy for 0customer using file system
4. Modified the downloaded file ( re arranged the columns and also the width of the columns) and saved it as .csv
4. Created transformations and uploaded the file to 0customer. It went though fine.
5. The requirement is to automate it. I am not able to upload the downloaded file from 0cust_sales to 0customer, even if i remove distribution channel, division and sales org
Following is the snippet of the file
Or there are any other options.
