AFVV-ISAVD and AFVV-IEAVD update

Hi All,

I am trying to update the fields - ISAVD, IEAVD, ISDD and IERD in table AFVV. I created a custom program that should update the said fields.

I need to know a BAPI that i can use. I already looked into BAPIs BAPI_ALM_ORDER_METHOD and BAPI_PROJECT_MAINTAIN but i didn't see the fields mentioned above in any of the BAPIs.

Thanks,

Isaac
