How to upload long text in CA02 Transaction

Hi,

I am getting a file with the following format.

Input File Record Layout:

Group# like PLKO-PLNNR,

Group Counter like PLKO-PLNAL,

Operation# like PLPO-VORNR,

Work Center# like PLPOD-ARBPL,

Control Key like PLPO-STEUS,

Short-text like PLPO-LTXA1,

Long-text type c(1000).

i have to upload the long text in the CA02 transaction. Could you please let me know the procedure that i should follow in uploading this in doing a call transaction in BDC.

Thanks in Advance,

Suresh
