Field Selection Keys

[brianloo]

The following are types of field selection keys for purchasing documents:

• Transaction
• Activity category
• Purchasing document type
• Item category
• Function authorization (EFB)
• Release status

The following list provides more detail about the field selection keys:

• Transaction field selection key:
  
  This field selection key is firmly linked to the transaction that you use. For the change contract transaction, for example, this is the ME32 field selection key. For the display contract transaction, it is the ME33 field selection key. For the Enjoy purchase order, there is only one field selection key, ME21N.
• Activity category field selection key:
  
  The following are the activity categories:
  
  • AKTH (for creating items)
  • AKTV (for changing items and all Enjoy transactions)
  • AKTA (for displaying items)
  • AKTE (for purchase order extension)
  • The Activity category field selection key is necessary because you can add an item in the change contract transaction (ME32), for example. You use the AKTH field selection key for this item.
• Purchasing document type field selection key:
  
  You can assign a separate field selection key to each type of purchasing document. For example, you assign the UBF field selection key to the UB document type (stock transport orders within a company code). This field selection key suppresses the Price and Price Unit fields.
• Item category field selection key:
  
  This field selection key is determined from the item category in combination with the document category. The first two characters of the field selection key consist of the letters PT, and the third character indicates the item category (internal representation). The fourth character represents the document category as follows:
  
  • A (for RFQs)
  • B (for requisitions)
  • F (for purchase orders)
  • K (for contracts)
  • L (for scheduling agreements)
  • For example, use the PT3F field selection key for a subcontracting item in a purchase order.
• Function authorization (EFB) field selection key:
  
  This field selection key controls the authorization for the price display or entry in the purchasing documents. If the EFB user parameter (function authorizations in purchasing) has been assigned to a user, this field selection key is also used.
• Release status field selection key:
  
  You can set the field status of a purchase requisition using the field selection key for the release indicator, depending on the respective release status of the purchase requisition.
