please help.

friends , please help.

i am supposed to a conversion of FI documents,

where an excel sheet is given which contains the data extracted form 4.7

now the names of the old G/L accounts and comp codes have changed, so first i have to change all the G/L accoutns, cost centers, internalorders to new ones,

then i have to upload all the data in ECC 6.0

before uploading i should do a validation program with the help of selection screen program to make sure, the cost centers etc, in the transaction data to be uploaded has the same cost centers available in ECC 6.

they have suggested me to use RFBIBL00 program.

has anyone done this previously, how to convert this file to be uploaded to be converted to required format.

thank you.
