Regarding tab control in MIR4 (ECC) *Sorry, The MIRO description has been corrected to MIR4.

*Sorry, The MIRO description has been corrected to MIR4.

I have the following customizations:

Material management > Logistics Invoice Verification > Incoming Invoice > Activate Direct Posting to G/L & Material Accounts

Customizing: Direct Posting in Log. Invoice Verification
         Check_ON    Dir. posting to G/L acct = active
         Check_ON    Dir. posting to matl = active

However, the "Material" tab is not displayed on the actual screen. Why is this? (The PO used in ERS have Material data.)

I would appreciate any advice.

When you activate “Direct Posting to G/L Accounts” and “Direct Posting to Material Accounts” in IMG, you expect both the G/L Account and Material tabs to appear in MIR4. However, SAP’s screen logic treats ECC and S/4HANA differently.

1. ECC MIR4 Behavior

• By default, standard PO-based invoice postings in ECC MIR4 hide the Material and G/L Account tabs, even if you’ve activated direct posting.
• You only see those tabs when you pick Subsequent Debit or Subsequent Credit from the invoice dropdown: this enforces the standard GR/IR reconciliation path and prevents accidental bypass of OBYC logic.

S/4HANA MIR4 Behavior

• In S/4HANA, SAP delivers a new screen variant for MIR4 that shows the Material tab on all invoice types once “Direct Posting to G/L & Material Accounts” is switched on.
• The logic behind OBYC and the need for subsequent postings remains the same—it’s purely an interface simplification.

Hi,Lakshmipathi

Thank you for your reply.

This is exactly what I'm seeing on the screen, and it makes perfect sense.

I understand this difference as a "change in behavior" between ECC and S4, but am I correct?
