• You can only generate SLS sub-items in collective purchase orders during the order generation process.

• A vendor cannot pass on SLS data to another vendor if the distribution involves more than one step.

• SLS sub-items cannot be assigned to a full product in a collective purchase order, as sub-items of a full product cannot be processed at goods receipt.

If the article master records were not created in SAP Retail article maintenance (but in a manufacturing system, for example), you have to assign the SLS to the articles involved using transaction WTAD_VKHM_MAINTAIN. You can display existing assignments in transaction WTAD_VKHM_DISPLAY.

• If you use transactions ME22 or ME23, you can only edit the quantities in the main items and SLS sub-items by choosing Item ® More functions ® SLS items.

• No further SLS sub-items can be added or deleted online.

• If you use transactions ME22 or ME23, you can display main items only, sub-items only or all items in the item overview screen. If you want to display all the items, the system displays the main items and sub-items on the same level. The number of the main item is not displayed at all as a reference in the sub-items.

• You cannot use merchandise-driven flow-through for collective purchase order items with SLS sub-items.

• The system distributes the quantity of a purchase order item as follows:

1. The main item quantity is distributed amongst the sub-items.
2. If schedule lines are used, the quantity is distributed as follows:

• The sub-item quantity is distributed to the schedule lines for the individual sub-items.
• The schedule line quantities for the main item are calculated from the schedule line items for the sub-items.

• If you want to highlight the SLS sub-items on the order printout or even print the SLS data separately, you have to change the order printout accordingly.

• If you receive an order confirmation from a vendor by EDI, the system only takes the information in the main items into account. Information on sub-items is ignored.

When you enter SLS sub-items in a sales order, a number of activities are required on the part of the user.

• The sub-items in the delivery are not relevant for picking. Therefore, they do not appear in the picking list. Neither are they contained in Warehouse Management transfer orders.

• If you want to highlight the SLS sub-items on the delivery note printout or even print the SLS data separately, you have to change the delivery note printout accordingly.

Only when the user packs online does the system issue a message indicating that SLS are required and check if sub-items can be packed in the shipping unit selected.

• You cannot post a goods receipt in the function for changing an inbound delivery.

• You cannot process inbound goods receipt IDocs that report goods receipts for collective purchase order items, containing SLS sub-items.

• One-step stock transfers are not supported. This means that you cannot post the goods receipt at the receiving site at the same time as the goods issue in the issuing site.

• At goods receipt, you cannot reference shipping units.

• When you are entering a goods receipt, you can only process the quantities for the SLS sub-items if the sum of the individual SLS sub-item quantities differs from the total quantity in the main item. When this is the case, the system automatically takes you to the screen for processing sub-items.

• Purchase order history records for SLS sub-items are only updated (and thus can only be displayed in purchase orders) if the quantity was corrected at goods receipt.

• The schedule line data for SLS sub-items is not updated at goods receipt.

• When a distribution is adjusted at goods receipt, the storage location for items with SLS sub-items is not determined for the different processing methods. If a storage location has been entered in the purchase order, this is proposed as a default which can be changed by the user.

• You can configure the system so that structured articles are broken down into their individual components at goods receipt. You cannot, however, have the system break down structured articles that contain SLS sub-items.
