Diagnosis
You want to post the reposting document entered, but reference itemV1 has not been fully reposted.
Reference item &V1& still contains a remaining amount or quantity to bereposted.

System Response
The CO line items selected have not been fully reposted. Therefore, thedocument cannot be posted. The SAP System proceeds to document itemV2 for processing.
A reference item is the same as a CO line item to be reposted. This canonly be reposted in its entirety. This means that the total quantityfor all document lines for a line item must be the same as the quantityfrom the original line items to be reposted.
The remaining quantity in a reference item is thus the differencebetween the total quantity of the line item to be reposted and the sumof all the quantities entered to this point in all document items forthis reference item.
When editing a document item for the first time, the SAP Systemautomatically defaults the remaining quantity to be reposted from theassociated reference item.
This value may be overwritten, but it cannot exceed the default value.

Procedure
Correct the individual reposting amounts in document item &V2& or inthe other document items belonging to document itme &V1& so that theamount and the quantity of the CO line item to be reposted iscompletely reposted to the document.
To view the reference item's remaining amount, use the RefItemfunction for document items entered for the reference. A dialog windowappears with the posting date of the corresponding reference item.
Post the document after the complete reposting of reference item datais completed.
