EPC number not accepted

Hi All

I am trying to simulate Slap & ship outbound sceanrio 2.1

i have done all the required configuration.

but when i supply PML to sap/scm/ain through AIN destination,it donot accept the EPC number provided in PML.

When i got through log it has following entries.

>>EPC 1 in the message is:

>>No document is used, Action type APL2 'Free Pack' is used

>>Header value 00000000 is not possible to convert to available EPC types

>>Company prefix index 0 does not exist for this GTIN 00000000000000000000000000000000000000000000000000

Can any one suggest what could be the problem?

Thanks

Mitesh
