R27451 Invoice - Line Amount Sign Restriction

Code	R27451
Entity	Crm.Invoicing.Invoices Entity
Name	LineAmountSignRestriction
Attribute	LineAmount
Layer	Back-End
Events	Planning +
Modify	NO
Action	For every line, validate that: If 'Invoice.DocumentType.InvoicesOption. SignRestriction == (-1) AllowOnlyNegative', then the sign of the 'LineAmount' is '-' ; If 'Invoice.DocumentType.InvoicesOption. SignRestriction == (0) AllowAll', then the sign of the 'LineAmount' is '-' or '+'; If 'Invoice.DocumentType.InvoicesOption. SignRestriction == (1) AllowOnlyPositive', then the sign of the 'LineAmount' is '+'.
** Description**	Acording to the particular business purpose of the Invoice, we are able to manually restrict the signs of the Line Amounts in the document. For example, using this option we can specify that the certain document can be used when returning goods (in this situation both Quantity and Line Amount are with negative signs) or not. The option is called 'Sign Restriction' and is set in the Entity Settings panel in the Document Type's definition. In order to assure that this restriction is not valuated - we need to check if the signs of the Total Amount in all document lines correspond to the value set 'Total amount Sign Restriction' for the particular document.
Message	The field 'Line Amount' in line '{Invoice.LineNo}' contains a value with an invalid sign. There is a sign restriction set in the document type definition, but the line amount sign violates this setting.
