required field (set by field property BADI) check if not entered

Hi, all.

I'm Derby Lim.

Set in field property BADI ( USMD_ACC_FLD_PROP_CUST_DEP_SET ) lots fields as required.

When I press check button, some(= only MATERIAL entity) fields are checked if not entered like showing following messages.

• Material $573: Enter a value for attribute Industry sector
• Material $573: Enter a value for attribute Material Group
• Material $573: Enter a value for attribute EAN/UPC

Other entities' fields are not checked if not entered.

I found that It works on entities have a self key. eg. MATERIAL, CARR.

How to fix it? to works on all entities?

Would l rather add custom required field check logic in rule badi for entities that don't have a self key?

Thanks in advance
