MAA: Net Value field Hidden for "Distribute by Amount" for Materials

Hello Experts,

We have recently activated the switch LOG_MM_MAA_1 in our system for activating "Distribution by Amount"
function in PR and PO.

For Services, system is working fine.

But, in case of Materials, on AAC screen, the Net price field goes hidden as soon as I use "Distribute by Amount" option.

With Distribution on Quantity:

With Distribution on Amount:

I checked / tried changing my Account Assignment Categy too but nothing worked.

In SPRO, the settings could be done for GR and Invoice but nothing for PO / PR.

I checked in BUsiness Function Test Case Description. It is stating, that with Distribution on Amount, user should be able to enter Amount.

Not sure, what setting I am missing.

Please advise.

Thanks in advance for your inputs.

Regards
