Error message "No Addon Product Version allowed"
To maintain the system landscape using the Maintenance Optimizer, you must maintain the affected technical systems in one or more product systems in transaction SMSY. The assignment of the products and product instances plays a deciding role.
For add-on products, in addition to the add-on, you must also assign the prerequisite basis product. However, the relationship between add-on and basis product is not immediately visible in each case. The most prominent example is the product SAP ERP ENHANCE PACKAGE for which the basis product SAP ERP 6.0 is prerequisite. The versions EHP 1, EHP 2 and so on are not described as successors to SAP ERP 6.0, rather, as prerequisite, they have SAP ERP 6.0 as the basis product version.
If the assignment of the basis product in SMSY is missing, the Maintenance Optimizer issues the following error message:
"No Addon Product Version allowed for transaction:
Name of your add-on product (20-digit number).
Program: CL_MOPZ_EVALUATE_INSTANCES====CP, include: CL_MOPZ_E54"
First determine the basis product in SMSY.
Select "Product Definitions" and search for your add-on product in the list.
When you double-click your add-on product version, the system displays the prerequisite product version in a detail dialog box at the bottom of the screen.
Then assign the basis product version to the product system. Flag both the basis version and the add-on product version as active (this is possible as of SAP Solution Manager (SolMan) 7.0 Support Package 22).
