How To Fix AJ619 - Document and contract have different currencies; conversion not possible

SAP Error Message - Details

• Message type: E = Error

• Message class: AJ - Billing program

• Message number: 619

• Message text: Document and contract have different currencies; conversion not possible

What causes this issue?

This message involves a problem with the currency conversion to the
euro.
You tried to reverse an existing document with the manual billing
transaction, but the currencies in the documents are different: The
current document has currency &v1&, while the existing document has
currency &v2&.
To convert correctly, the price used must be defined in both
currencies. The price for both currencies must be identical in both the
time slices and the blocks.
Please note the following when converting the price and net amounts:
The net amount is converted to the euro using the valid conversion
rate. The price amount is taken from the price table. This results in
the following problem:
Normally, the net amount is calculated by multiplying the quantity by
the price. Because the price amount from the price table can be
different due to the mathematical conversion to the euro, multiplying
the quantity times the price amount does not necessarily result in the
displayed net amount.
Example:
<ZH>Old document in DM:</>
Price amount in DM ,,1.00 / kWh
Quantity,,100 kWh
Net amount in DM ,,100.00
Price in EURO,,0.5*
*The exact price in EURO is 0.51129...
Before the transfer to the new document, the net amount is multiplied
by the defined conversion rate. The new price amount is taken from the
table.
<ZH>New document in EURO:</>
Price amount in EURO ,,0.5 / kWh
Quantity ,,100 kWh
Net amount in EURO,,51.13 EURO
The net amount differs due to rounding the EURO price before
multiplying the price by the quantity.
A simple multiplication would result in a net amount of 50.00 EURO.
