Imposible to update Z-Fields appended to EBAN

Question

Hi gurus
There are Z-fields added to the table EBAN (purchase requisition) and wish to modify the value of these fields through a BAPI (BAPI_PR_CHANGE)
I know that I have to do by filling out the parameters of the table EXTENSIONIN but I have done all the tests possible and couldn't
I call BAPI_PR_GETDETAIL to see how fills EXTENSIONOUT table and then i put the same parameters into EXTENSIONIN to call BAPI_PR_CHANGE and no results
These are the Z fields added to EBAN
PRIO_REQ <----- This is the last standard field of EBAN
.INCLUDE CI_EBANDB <---- Include where Z-fields are in
ZBUYER     ZBUYER     CHAR     12
ZNMBUY     ZNMBUY     CHAR     30
ZBUQUE          CHAR     20
ZMOTOR          CHAR     20
ZNPARTE          CHAR     6
ZBUYER2     ZBUYER2     CHAR     12
ZBUYER3     ZBUYER3     CHAR     12
I see that the Z-fields are added on INCLUDE, not APPEND and i don't know if this is a problem, otherwise i hope someone can bring some ligth to this because is a big problem, i only can update these fields throug ME52N and can't make batch input to this transaction
Thanks

HI
Try to implement the Business addin ME_BAPI_PR_CUST
i.e., the method INBOUND.
and check the changing parameter CH_EXTENSIONIN
I think the badi will be triggered for the bapi BAPI_PR_CREATE, check if the same is useful for BAPI_PR_CHANGE as well.
