Invoice and PO / GR with different amount values

Hello all,

We use ERS (invoicing by MRRL) and we have a problem concerning differences in amount values of an invoice and purchase order / material documents.

Analyzing EKBE table, and considering for comparison a correct invoice previously created with reference to the same purchase order, we can verify that some fields don’t follow the same logic:

Correct Invoice:

MENGE = BPMNG = 40.455

DMBTR = WBRTR = REEWR = REFWR = REWRB = 414.66

AREWR = AREWW = AREWB = AREWR_POP = 414.66

Incorrect Invoice:

MENGE = BPMNG = 41.992

DMBTR = WBRTR = REEWR = REFWR = REWRB = 265.41

AREWR = AREWW = AREWB = AREWR_POP = 430.42

Note that the material price is 10.25 EUR in both invoices.

Can someone help us with this issue?

Thanks in advance.

Best regards,

João Salgado
