SAP configuration allow for the blocking of invoices based on value at line item level. The configuration works well when the invoice line item is over the threshold value. In adition the following scenario needs to be caterred for:
Transaction MIRO and MIR7
When there is more than one item line on the invoice and the total sum of the two lines exceeds the determined threshold value, the invoice should be blocked when saved or saved as complete. I.e. The invoice header threshold value is R200k and there are two line items of R100k and R105k each. The combined value at header level is R205k and exceeding the threshold value of R200k.
If Invoice header:INVFO-WRBTR > R200k and Payment block field:INVFO-ZLSPR ≠ Invoice verification then change to Invoice verification and save.
