Setting Up Field Selection in Purchasing Documents

You use the field selection keys to define the field status for all documents types.

A field selection key determines whether the following applies to a field:

• Entry is not possible because the field is suppressed (hidden or suppressed field).

• Entry is not possible, but the value of the field is displayed (display field).

• Entry is mandatory (entry required field).

• Entry is optional (entry optional field).

Each individual factor in the preceding figure influences the attributes of fields.

If the attribute of a field is determined variously by several factors, the following linkage schema applies:

For example, when creating a standard purchase order with the Standard item category, the system determines the following field selection keys and settings for the Material Group field:

• ME21N field selection key (transaction):

  The Material Group field is an optional field.

• AKTV field selection key (activity category for all Enjoy transactions):

  The Material Group field is an optional field.

• NBF field selection key (NB purchasing document type):

  The Material Group field is an optional field.

• PT0F field selection key (Standard item category):

  The Material Group field is a mandatory field.

The combination of the field selection keys ME21N, AKTV, and NBF means that the field is an optional field. However, because the Material Group field is defined as a mandatory field in the PT0F field selection key, this means that the field requires an entry when you create a purchase order.

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.
