COPA Planning-Upload via KE13N

Hi Experts ,

I am doing COPA planning , but stuck with the excel upload via T code KE13N.

-I have defined the planning level on the basis of the sales organisation

-Planning packages on basis of years.

-Paramater set has also been defined. Integrated excel is checked here .

-While saving the planning layout i have defined the coloumns for Company code, distribution channel, division as Lead columns.

When i am trying to execute the parameter set, excel gets generated. i am unprotecting the excel and doing the changes in layout, Since i want Characteristics in rows and Values in their corresponding columns . i save that excel to my desktop in text format.

After this in KEPM i goto settings > fomatting > Save file description.

It gives me mesage " File description 02_CE1CA00__SAP_001TEST7 was saved"

After this i goto KE13N and trt to upload the text file i created before but i get the error message

"File description 02_CE1CA00__SAP_001TEST 7 does not exist".

Cld u pls advise where i am going wrong .
