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,

I'd like to refresh the record of the service in ESLL\ESKN (using suitable BADIs or enhancement points at PO Order), but not to oblige the user to enter the "Services" tab. I need to refresh the data in the record because I've made a changes in a Z-field in EKPO.

I'd really appreciate your help, thank you 🙂
