When Using SAP APO 3.0A or Earlier Releases

Under certain conditions you can change items in a sales order in CRM Enterprise after it has been replicated in SAP R/3 Enterprise.

However, if you are using SAP APO 3.0A or earlier releases, there are certain restrictions when you are changing items which are relevant for availability check in SAP APO. These restrictions come into effect if an item relevant for availability check has been partially or fully delivered. The reason is that in SAP APO 3.0A and earlier releases, it is not possible to carry out consumption for goods issues such as deliveries which have taken place.

Therefore, you cannot change any fields in the schedule lines for these items. You can only change on item level those fields which have no influence on functions which take place in SAP APO. This means that if you need to raise the quantity of an item, you will have to create a new item.
