Problem with BAPI_PO_Create1 to create a Service PO

Question

Hi,
I use a piece of test to create a service's po with data:POHEADER,POHEADERX,POITEM,POITEMX,POSCHEDULE,POSCHEDULEX,POACCOUNT,POACCOUNTX and POSERVICES.
In POSERVICES, I enter the data like this:
LINE_NO                        0000000010
OUTL_IND                      X
QUANTITY                    100.000
BASE_UOM                   EA
GR_PRICE                     1,000.0000
SHORT_TEXT               SERVICE1
but when i excute it, the return with message:
T ID                   NUM MESSAGE
E BAPI                001 No instance of object type PurchaseOrder has been created. External reference:
E MEPO              000 Purchase order still contains faulty items
E SE                   029 Please maintain services or limits
according to the third msg, I have maintain the value for it, why it said 'Please maintain services' ?
Best Regards
Steven

Hello Steve
The long text of message SE 029 says that
"You cannot enter data until the PO item has been maintained correctly."
Because the input for the item is still faulty you get this addtional error message.
My recommendation is (because I am not a MM expert): Try to create a minimal service PO using the dialog transaction. All values you have to enter in dialog are needed for the BAPI, too. Perhaps then you spot the missing piece of information.
