For an order to be automatically opened immediately after a planned order or purchase requisition is
transferred
to the SAP R/3 system (that is, the order is automatically immediately converted into a manufacturing order or purchase order in the SAP R/3 system), the conversion indicator must be set in
Production Planning and Detailed Scheduling
(PP/DS) before this order is transferred. There are different ways of doing this:
Manually for any orders in the product view , in the order processing view or in the receipt view
Manually or automatically before the mass transfer of orders to the SAP R/3 system
Here, you set the conversion indicator specifically for orders that are waiting for conversion, that is, whose planned opening date is in the past.
Automatically for the conversion of SNP and CTM orders into PP/DS orders .
Recommendation
Basically, you should only trigger conversion of a planned order into a manufacturing order in SAP R/3 by setting the conversion indicator in SAP APO. Only by doing this, can the dates planned in SAP APO be retained.
For more information, see Setting the Conversion Indicator
Using the conversion checks , you can exclude orders from the transfer and conversion if they do not fulfill specific business prerequisites. For example, you can use an ATP check, which examines the availability of components, as a conversion check.
