Flat file: loading Master data questions

Hi Experts,

1

If I have a flat file with columns, Columns1, Columns2, Columns3, and we load this manually to an ODS monthly.

a.

Where in BW can I see the exact match to the columns, Columns1, Columns2, Columns3?

b.

What will be the effect of receiving the flat file from the user this month if the columns are not in the usual order e.g. Columns3, Columns2, Columns1?

2..

I have an Info Object CustCode_10, check with Text (Medium description) and it also has an attribute CustDispl_11.

a.

What should be the format of the flat file in order to get in the Master data?

b.

After loading a flat file, I can go to the infoobject CustCode_10, right click and select Maintain Master… to see the master data. How do I see the data in the Attribute.?

Thanks
