Safety days supply Error

Hi All,

I am testing the safety days supply (SZ) method, assigned the method SZ in product master, and maintained safety days of supply.

Using the 9asnp05 planning area and standard planning book 9ASNP_SSP. But the safety days supply is not displayed in the planning book key figure from product master.

Found out that the Safety days macro is not part the planning book, and hence created the new planning book based on the standard planning book.

Created the safety days supply macro as below

Safety Days : ( 25 Iterations :22.08.2013; W 43.2013 )

Row: Safety Days' Supply ( Frm 23.08.2013 ) =

SAFETY_DAYS( ACT_PRODUCT ; ACT_LOCATION ; ACT_VERSION )

However the safety days are not displayed in the planning book.

I am able to enter the data in the key figure manually, if I enter the days 5 and later if i change 8 the safety stock data not calculated based new data.

Help me out where the mistake is.
