Only relevant if the "Association active" indicator is not set. The "Association active" indicator overrides this setting. If you set the "Reassociation active" indicator, special association handling is activated which may be particularly useful for documents on the purchasing side:
The association on the fly dialog box of the Trading Execution Workbench is not called.
In subsequent actions, such as create delivery, association-specific quantity checks are not carried out.
If you selet this indicator for the business process step "inbound delivery", you can create inbound deliveries for purchase orders without associations having been created beforehand.
