Issue in applying derivation rules after custom field change

[former_member207791]

Hi Gurus

I have added a custom field in the table EKPO which is listed in the item level in the "Internal" tab in me21n, me22n and me23n. the field is getting updated and saved as it should. But, I have also defined derivation rules which apply to the fund field in the ESKN and EKKN tables. The derivation rules only apply when I go to the "Services" tab at the item level and I click on "Account Assignment" after saving. I want the derivation rules to apply as soon as I save the custom field without going to the "Services" tab.

How to I make the derivation rules apply ?
Is it possible to do it through the badi exit_sapmm06e_018 ?

Thank you.

Hello Ankur

I looked for table ESLL at BADI "ME_PROCESS_PO_CUST" but couldn't find.

There is any function mudule to use at this BADI that help me make the derivation rules apply ?

Thank you.

Hello Jude, yes you need to find FM, because in the table ESLL there is package number generated once we saved the PO, so this we cannot check in the runtime while creating PO, but you can check the same in ME22n through the same BADI.

Thanks,
