How To Fix WP131 - Currency missing in sales document

SAP Error Message - Details

• Message type: E = Error

• Message class: WP - Messages from POS interface

• Message number: 131

• Message text: Currency missing in sales document

What causes this issue?

The document currency cannot be determined.
The document currency is the currency in which prices and conditions of
the sales document were transferred. It can differ from the currency
used for payment.
The document currency can be defined in the sales document. If it is
missing, the POS currency is used from the store master. In this case,
however, there is no currency in the sales document nor in the store
master.

System Response

The document is posted with the company code currency of the store.

How to fix this error?

If you are absolutely sure that sales documents from the store are
always posted with the company code currency, you can ignore this
warning. If the currency is being converted in the POS system or in
R/3, you should take one of the following measures:
If the POS system in the store allows it, you should have the currency
entered in the sales document. This is the safest method.
Enter the POS currency in the store master. The store master must be
converted at the same time as the POS system. Only by doing so can you
ensure that the correct currency can be found for every sales document.
You can fill the sales document currency using function exit
EXIT_SAPLWPUE_200 of enhancement WPUE0002.
You can have the POS converter fill the sales document currency.
If the document currency is neither available in the sales document nor
in the store master, sales documents are posted using the company code
currency. This would be wrong, however, if the currency used by the POS
system in the store differs from the company code currency. Even if you
take the proper organizational steps to ensure that the currency in the
store is converted at the same time as the currency in the company
code, serious problems could still occur. These can occur, for example,
when sales documents created before conversion are only posted after
conversion or when sales documents contained errors, were changed or
cancelled.

  Error Message
  WP131 - Currency missing in sales document
  
  Cause
  This error occurs because the sales document (such as a sales order, quotation, or contract) does not have a currency assigned to it. The currency is a mandatory field in sales documents since pricing, conditions, and billing depend on it.
  Common reasons for this error include:
  
  The currency field was not entered or maintained during document creation.
  The customer master record does not have a default currency assigned.
  The sales document type or item category configuration does not default a currency.
  Data transfer or interface issues where currency information is lost or not passed correctly.
  Custom enhancements or user exits that inadvertently clear or fail to set the currency.
  
  
  Solution
  To resolve the WP131 error, ensure that the sales document has a valid currency assigned:
  
  
  Manually Enter Currency:
  
  When creating or editing the sales document, enter the currency in the header or item level currency field.
  Usually, the currency is entered in the sales document header (field: WAERK).
  
  
  
  Check Customer Master Data:
  
  Verify that the customer master record (transaction XD03 or VD03) has a default currency assigned in the sales area data.
  If missing, maintain the currency in the customer master (transaction XD02 or VD02).
  
  
  
  Check Sales Document Type Configuration:
  
  Ensure that the sales document type is configured correctly to default the currency.
  Use transaction VOV8 to check sales document type settings.
  
  
  
  Check Pricing Procedure and Condition Records:
  
  Sometimes, missing currency can be related to pricing conditions.
  Verify condition records and pricing procedures to ensure currency is properly maintained.
  
  
  
  Review User Exits or Enhancements:
  
  If custom code is used during sales document creation, check that currency is not being cleared or overwritten.
  
  
  
  Data Transfer / Interface Checks:
  
  If the sales document is created via IDoc, BAPI, or other interfaces, ensure the currency field is correctly mapped and passed.
