APO-ABAP: Location master populating additional fields

Hi All

Whilre doing CIF from ECC to APO we want to populate some fields based on ECC data in location master ( t code '/SAPAPO/LOC3') .

Fields in additional tab such as CTX_ATTLO01,CTX_ATTLO02

location for sold to party in VMI CUst..section i.e. field VMI_LOCNO.

I can see these fields in t code '/SAPAPO/LOC3'.I have tried implementing BADI 'SMOD_APOCF001' but these fields are not available in any of the import parameters.

Any other user exists? or am i missing something.

Please advise.

Thanks,

Dev
