Transfer material production version from COPA to SOP

Hello all,

We are currently loading our sales plan in COPA using KEPM and then we transfer the plan to SOP using KE1E, so far so good.

The sales plan is stored on S076 table. This table has a field for "production version" and we would like to populate this field with right production version.

Our issue is: We are able to add the production version in KEPM but when we transfer to SOP the production version is not transfered\stored in S076.

Is this a configuration issue or is not possible to include the production version by material in COPA and then transfer to SOP?

Thanks in advance.
