progrqming help needed

Hi ,

I have on selection screen of the program the file name which uploading our stock.

It looks like this:

PARAMETER: p_name LIKE epsf-epsfilnam

DEFAULT 'STOCKDDMMYYYY02.txt'.

INITIALIZATION.

REPLACE 'DD' WITH sy-datum+6(2) INTO p_name.

REPLACE 'MM' WITH sy-datum+4(2) INTO p_name.

REPLACE 'YYYY' WITH sy-datum+0(4) INTO p_name.

for example this is ok for today, but how I can set that the program will check sy-datum - 1day? This means, I want to have yesterday date written here...

Thanks for the answer

Saso
