Processing
Associations 
You can maintain associations during sales document processing, using the Trading Execution Workbench (TEW).
This function is called when you create follow-on documents.Before you are taken to the document maintenance screen the system asks you to check association data. You must carry out the association step in full before you can proceed. However, if the document item is completely and uniquely associated this association step is carried out automatically.
· The selected document must have the status Released.
· Only a trading contract in which logistics follow-on documents are processed can be selected as a source document.
· When creating a contract, a portfolio must be assigned to the relevant document item.
...
1. In the TEW initial screen, you select the necessary parameters in the Task areaand define the source document selection range.
The list of source document headers and source document items appears in the middle of the screen.
2. You select the source document headers and/or source document items.
3. The association maintenance screen opens in a separate screen.
Two different cases exist here:
a. The document item is complete but is not uniquely associated.
Association partners and quantities are displayed in the lower list. Now perform cross-referencing.
b. The document item is not completely associated.
Association partners and quantities are displayed in the lower list, as are association candidates. You can change association partner quantities directly. If you want to enter a quantity for an association candidate you select the appropriate line. Choose Change entries and enter the quantity. Now perform cross-referencing.
4. To get to the screen for maintenance of logistics documents, choose Copy data.
