In SAP Business One, you can cancel most sales and purchasing documents that normally trigger postings. When you canceled such a document, a corresponding cancellation document is created to reverse the associated accounting, tax, and inventory changes. The base documents of the canceled documents are reopened with balances due restored. 

In the intercompany document exchange cycle, when a user cancels a document, the application automatically cancels the reciprocal document.

In the intercompany document cancellation, the following four cases are handled:

1. When you reject the intercompany type draft document in the receiver company, the application closes the draft document. This rejection creates the cancelation document in the sender company.
   
2. When you cancel the intercompany document in the sender company, the application closes the draft document in the receiver company.
   
3. In the receiver company, when you add the draft document to the company document and then you cancel the document in the sender company, the firm document is canceled in the receiver company.
   
4. In the receiver company, when you cancel the company document, the company document is canceled in the sender company.
   

Example

Delivery to Goods Receipt PO Document Exchange Cycle

Company B creates a delivery to be made to Company A. The delivery document creates a draft goods receipt PO in Company A. 

Case 1: 

In Company A, if you reject the draft goods receipt PO, the application closes the draft document. The rejection creates a delivery - cancellation document for the delivery document that was added earlier by Company B.

In Company B, if you cancel the delivery document, this closes the draft goods receipt PO in Company A.

If Company A adds the draft goods receipt PO to a company goods receipt PO document and Company B cancels the delivery document, then the goods receipt PO is canceled in Company A.

Case 4:  

In Company A, if you cancel the goods receipt PO, this cancels the delivery document in Company A.
