It is accordingly an object of the present invention to provide a system and method of consolidating information for display by EPLs. An embodiment of the present invention will now be described by way of example, with reference to the accompanying drawings, in which: Fig. 1 is a block diagram of a transaction processing system; and Fig. 2 is a diagram showing data files used within the transaction processing system; Fig. 3 is a flow diagram illustrating the method of the present invention. Referring now to Fig. 1, transaction processing system 10 primarily includes host computer system 12, point-of-sale (POS) system 14, EPL system 16, and business information systems 18. Here, components 12, 14, 16, and 18 are shown as separate components that are networked together, but they may also be combined in different ways to form less components. Thus, host computer system 12 may be a POS terminal which doubles as a host computer for network of other POS terminals. Also, host computer system 12 and business information systems 18 may be combined into a single system. POS system 14 includes bar code reader 19 and terminal 20. EPL system 16 primarily includes EPLs 22, host EPL terminal 24, and EPL storage medium 26. EPLs 22 include control circuitry 52, data registers 54 and displays 56. Control circuitry 52 receives and transmits messages from EPL terminal 24 and controls display of information by display 56. Control circuitry 52 stores data within the messages, such as price, promotional, and business information, in data registers 54. Business information is employee-directed information which is of primary interest to employees, rather than customers. Business information may be displayed alone, or in combination with price information. In the latter case, business information is displayed in portion 58 while price information is displayed in second portion 59. Both types of information may be in separate registers and/or may be combined into a single data message prior to transmission to EPL 22. Host EPL terminal 24 executes EPL software 30. To assist with execution of certain tasks performed by EPL software 30, EPL terminal 24 includes a built-in time keeping device, commonly referred to as a system clock, which is synchronized with current time, in order to automatically execute the tasks at their scheduled times. EPL software 30 is responsible for scheduling and transmitting data to EPLs 22. EPL software 30 obtains prices in price look-up (PLU) data file 46 as they are entered in input device 40 or after they have been stored within PLU data file 46. EPL terminal 24 also executes data consolidation software 34, which consolidates business information for display. More specifically, data consolidation software 34 obtains the business information, formats the business information into codes for display, and maps the codes into data registers 54. The codes occupy minimal space in data registers 54. Data consolidation software 34 obtains business information from business information data files 48 in business information systems 18 or from direct input through input device 40. Data consolidation software 34 manages consolidation data file 38, which maps each EPL 22 to business information types and register locations. EPL storage medium 26 stores EPL data file 32 and consolidation data file 38. EPL storage medium 26 and is preferably a fixed disk drive. EPL data file 32 contains EPL identification and checksum information. Checksum information is calculated from price information in PLU data file 46. EPL data file 32 contains current information displayed by EPLs 22. Input device 40 is preferably a keyboard. Host computer system 12 includes PLU storage medium 44, and transaction server 42. Transaction server 42 handles price requests from POS terminal 20. POS terminal 20 sends item identification information to transaction server 42 and transaction server 42 returns the corresponding price from PLU data file 46. PLU storage medium 44 stores PLU data file 46. PLU data file 46 is available for distribution to POS terminal 20. Provision may be made for direct access to PLU data file 46 by bar code reader 19. Business information systems 18 include information sources and associated business information data files 48. Business information systems 18 maintain information for managing the transaction establishment, such as inventory information, shelf talker type, average item movement, plurality of facings for an item, plan-o-gram compliance information, and re-order information. Business information data file 66 may be a database, data warehouse, plan-o-gram database, in-store data file, or other source of business information. Business information in business information data files 48 is available for distribution to EPL system 16. Turning now to Fig. 2, EPL data file 32, PLU data file 46, and consolidation data file 38 are shown in more detail. EPL data file 32 includes a line entry for each EPL 22 in EPL system 16. Each line entry should have an item identification entry (ITEM ID), an EPL identification entry (EPL ID), an EPL checksum value entry (EPL CHECK), and a business information entry (BUS CODE). Entry ITEM ID identifies a store item. Entry EPL ID identifies which EPL is assigned to the item. Entry EPL CHECK is a checksum value of the digits of the price information that is displayed by display 56. Entry BUS CODE is a code containing business information to be displayed by EPL 22 and storage information for storing the business information. PLU data file 46 includes a line entry for each item sold in the transaction establishment. Each line entry has at least an item identification entry (ITEM ID) and a PLU price entry (PLU PRICE). Entry ITEM ID identifies a store item. Entry PLU PRICE identifies the price read by POS system 14 to determine the price of each item during scanning by bar code reader 19. Consolidation data file 38 preferably includes a record for each EPL (EPL ID) in the transaction establishment, although some stores may desire fewer records. Each line entry in the record includes a business information type entry (BUS TYPE), a data register plurality entry (REG NO), a display position entry (DISPLAY POS), and a display length (DISPLAY LENGTH). Entry BUS TYPE identifies the source or sources of business information to be coded and displayed. For example, business information types (BUS TYPE) may include inventory information, shelf talker placement information, average item movement information, plurality of facings for an item, plan-o-gram compliance information, and re-order information. Entry REG NO identifies the plurality of the data register in which the business information will be stored. Entry DISPLAY POS identifies the position of the business information in the display. Entry DISPLAY LENGTH identifies the length of the business information, including a preceding space as necessary to separate it from another type of business information in a previous position. Business information data files 48 are sources of different types of business information. Each business information data file 66 typically includes line entries for items sold in the transaction establishment (ITEM ID) and business information (BUS INFO). For example, one type of business information data file 66 could be an inventory data file containing latest inventory information about merchandise items sold in a transaction establishment. During normal operation, data consolidation software 34 creates entry BUS CODE from configuration information in consolidation data file 38 and business information in business information data files 48. Data consolidation software 34 obtains business information types for an EPL 22 from consolidation data file 38. Data consolidation software 34 then obtains business information from business information data files 48 identified in the BUS TYPE entries for the EPL 22. After retrieving the business information, data consolidation software 34 consolidates the business and configuration information into a business information code (BUS CODE). For example, an operator may add the following line entries to an EPL record in consolidation data file 38: BUS TYPE REG NO DISPLAY POS DISPLAY LENGTH BIB 4 1 1 INVL 4 2 3 MVMT 4 5 4 Where the "BIB" value is "0" if a shelf talker is not installed and "1" if a shelf talker is installed, the "INVL" value is a current inventory level for the item associated with EPL 22, and the "MVMT" value is the average movement value for the item. If data consolidation software 34 determines from consolidation data files 66 that BIB=0, INVL=50, and MVMT=945, then data consolidation software 34 consolidates the above information into a business code entry in EPL data file 32 of "1 50 945". Data consolidation software 34 then causes EPL software 30 to schedule a message for transmission to EPL 22 which contains the business information code and a command to store and display the encoded business information. Control circuitry 52 within EPL 22 receives the message, decodes the business information code, stores the business information in the data register 54 identified in the business information code, and causes display 56 to display the business information in portion 58 in accordance with display position and length information in the business information code. Referring now to Fig. 3, the operation of data consolidation software is illustrated in detail, beginning with START 70. In step 72, data consolidation software 34 reads a record in EPL data file 32. In step 74, data consolidation software 34 identifies an item identification plurality (ITEM ID) and an EPL identification plurality (EPL ID) in the record. In step 76, data consolidation software 34 reads an EPL record in consolidation data file 38 corresponding to the EPL identification plurality (EPL ID). In step 78, data consolidation software 34 identifies the types of business information (BUS TYPE) in the EPL record in consolidation data file 38. In step 80, data consolidation software 34 reads the business information data files 48 to obtain the identified types of business information for the item (ITEM ID) associated with the EPL (EPL ID). In step 82, data consolidation software 34 reads operator-entered configuration information including a register plurality (REG No), a display position (DISPLAY POS), and a display length (DISPLAY LENGTH). In step 84, data consolidation creates a business information code (BUS CODE) by combining the business information with the configuration information. In step 86, data consolidation stores the business information code (BUS CODE) in EPL data file 32. In step 88, data consolidation software 34 causes EPL software 30 to schedule a message for transmission to the EPL 22 which contains the business information code and a command to store and display the encoded business information. Control circuitry 52 within EPL 22 receives the message, decodes the business information code, stores the business information in the data register 54 identified in the business information code, and causes display 56 to display the business information in portion 58 in accordance with display position and length information in the business information code. To the extent that EPL 22 was storing and displaying other information in the data register 54 and display portion 58, EPL 22 ceases storing and displaying the other information. Communication bandwidth may be conserved by updating only one register with multiple pieces of information. In step 90, data consolidation software 34 determines whether the record is the last record in EPL data file 32. If not, operation returns to step 72. If so, operation ends at step 92. Advantageously, the present invention efficiently displays helpful business information while minimizing storage and display area requirements in EPLs. The present invention allows several pieces of business information to be displayed without disrupting the display of price information by the EPLs. Although the present invention has been described with particular reference to certain preferred embodiments thereof, variations and modifications of the present invention can be effected within the scope of the invention.
