This exit concerns the list of materials for the criteria customer number, material group, search string and language.
This list is created by function module QC07_CUST_SAREAS_MATERIALS_GET. It is called by the RFC-capable function module BAPI_CUST_SAREAS_MATERIALS_GET.

The following possibilities are available:

• Based on the criteria, you determine that no list should be output.
• You would like to carry out your own material selection, instead of using the standard module selection.
• You are using the standard selection, but would like to rework the materials list, before it is sent out.

• Certain customer groups should be denied access to the list of materials.
  You are using module EXIT_SAPLQC07_003 to read in data (customer group) using the customer number. Based on this data you can decide whether a list may be created (confirmation parameter E_NOT_ALLOWED initial), or not (E_NOT_ALLOWED activated).
• You would like to put together a list of materials for a customer from various tables. It should only contain materials for which an agreement was reached with the customer.
  You are using module EXIT_SAPLQC07_004 to carry out your own selection. Afterwards the list of materials is complete, i.e. no further products should be read. You have to fill export parameter E_STOP_SELECTION.
• You can use the predefined selection, but you should subsequently limit the product table on a customer-specific basis.
  You are using module EXIT_SAPLQC07_005 and
