Cash Discount Base field is inactive in MIRO

[SAPSupport]

Cash Discount Base field is available in FB60 transaction screen for being entered manually. We are expecting the same functionality in MIRO transaction as well.

We have this requirement as one of the Inbound Interface is sending the Invoice data with Case Discount Base value as well. So, it is predefined value and we're not expecting the system to auto-calculate it.

We need assistance in achieving this from SAP with any of the standard configurations or BADI’s could be implemented to bring this requirement into function.

As per SAP Note 904652, cash discount base amount (BKPF-SKFBT) is one of the FB60 fields that are not available in MIRO.

The field was removed from MIRO to simplify the entry logic, in such a way that only the cash discount amount or percentage is necessary, while the system performs automatic calculations for other fields.
You can get more information about that in KBA 2674327 - The cash discount base amount field (SKFBT) does not exist in Transaction MIRO.
