hi,
just check note: 351303 to populate et_extension1 and ~2 on ECC side.
On EWM-side you use Enhancement spot: /scwm/es_esp_mapin
I implemented BAdi definition: /scwm/ex_erp_mapin_od_saverepl
method: mapin to read my custom fields from segment Extension1; There I put them into some custom-fields (Z-*) of a structure which is used in table /scdl/db_reqh and table /scdl/db_proch_o.
reg., Walter.
