3555492 - Mandatory Custom Field Check not executed in ME21n without opening Custom Fields tab

• While creating a purchase order using ME21n, a custom field is set to obligatory in MM_PUR_S4_PO_FLDCNTRL_SIMPLE_H.
• The check for obligatory is not executed if the custom fields tab is not opened.
• The issue arises because the field can be saved without any entry if the custom tab is not opened.

1. Create a purchase order using ME21n.
2. Do not open the custom fields tab.
3. The check for obligatory is not executed.

The issue arises because the field can be saved without any entry if the custom tab is not opened.

1. The app “Manage Purchase Order” is implemented in a way that the business logic ensures that mandatory fields have a value and not the field control.
2. To ensure that a custom field has a value before the purchase order is saved, use either the BAdI MM_PUR_S4_PO_MODIFY_HEADER or BD_MMPUR_FINAL_CHECK_PO to implement the check.
