Error msg reqd in SD Proforma invioce
We are facing the below problem.
We create proforma invoice. With respect to this proforma invoice, Excise invoice is generated (Stock transport within same company,without billing).
User sometimes forget to enter the basic price in proforma invoice. System then issues an message No V1-801 (pricing error: Mandatory condition missing) but allows to save the document and proceed further.
As a result , when the excise clerk creates 'Excise document"with respect to this proforma invoice, the excise base value is zero. This is creating major problem in excise .
This message is not customizable (SAP confirmed this).
Then we tried to generate an error message -if the condition is missing or xontain zero value- through BADI
named "BADI_SD_BILLING_ITEM". But this BADI is for SAP internal use
only. It is not allowing us to work on it (OSS note 864944).
Please suggest how we can generate an error message for this situation.
