[Operation]
In the workflow management system configured as described above, since the workflow control unit 113 is executed after the authority confirmation by the authority control unit 112 is approved and there is no problem in authority authentication, the matter number included in the email is keyed. If the case content table 118 is searched and the text description content of the email 103 or 104 is added and the MessageID of the SMTP header is updated, and the control command content of the email 103 or 104 is approved (the approval flag is When ON, the route definition table 114 is referred to using the workflow ID of the case table 117 as a key, and the route ID in the same workflow ID is updated to the route ID of the case table 117. Further, after the information is registered, the workflow generation unit 109 stores the information and the case number that are input by numbering the case number in the case table 117 and the case content table 118, and the SMTP header of the e-mail 103. The item number is written in the field No. 1 and the client 101 and the mail client 108 operate to send an e-mail to the next business processor.

  As shown in FIG. 2, the detailed operation of the workflow control unit 113 includes step S201 for acquiring screen configuration information (workflow ID, screen ID, screen name) from the screen definition table 115, and a screen item definition table 116. Step S202 for acquiring configuration contents (screen ID, item ID, item name, component ID), and an input screen (combo combo) based on the screen configuration information and screen configuration contents acquired in steps S201 and 202 on the display unit of the client 101. Step S203 for generating a box, a text box, etc.), and a step for the user to register the case basic information (case No, Message ID, route ID, workflow ID) using the input screen generated by step S203. S204 and step S204 Step S205 for assigning and registering the entered case basic information in the case table 117 and registering the route definition information (route ID, workflow ID, and activity) using the workflow ID of the screen definition table 115 from the route definition table 114 as a key. Step S206 for generating a route based on the name, the person in charge of the route, and the processing content), and the matter number assigned in Step S205 is entered in the SMTP header of the e-mail, and the e-mail 104 is transmitted to the next processor. At the same time, by executing the step S207 for transmitting the dummy e-mail 103 to the next system, after registering the case information, the case number 117 is assigned to the information and the case number that are input and the case number is entered. 118 and SMT of e-mail 103 Write transactions No header operates to send to the client 101 and the mail client 108 to perform the following operations Processor.

  After the mail client 108 receives the e-mail 103, the mail receiving unit 110 acquires the case information from the case table 117 using the case number of the SMTP header given to the e-mail 103, and the MessageID of the acquired case information If the message ID is empty, the process ends as a newly registered case, and if the Message ID is not empty, the information is retrieved from the case table 117 again using References, which is the SMTP header of the e-mail 103, as a key. At this time, if the case information exists, it is determined that a normal e-mail has been transmitted, and the case number is acquired. If the case information does not exist, the process is terminated and a mail reply for return is performed.

  The mail receiving unit 110 executes the same processing as described above even when the transmitted email is the email 104 (processing instruction from the client 101). In this case, the email 104 includes the email text. Since the Message ID of the case information acquired from the case table 117 is not empty, it is determined that the existing data is updated.

  As shown in FIG. 3, the detailed operation of the mail receiving unit 110 includes a step S301 in which the mail client 108 of the server 105 receives the electronic mail 103 as shown in FIG. 14, for example, and an SMTP header of the mail received in the step S301. Step S302 for acquiring item information from the item table 117 using the item number included in the item as a key, and determining whether the Message ID of the item information in the item table acquired in step S302 is empty. Step S303 to be completed, Step 304 for extracting the case information from the case table using the References in the SMTP header of the mail as a key when it is determined that it is not empty, and the case information extracted in Step S304 exist. If it is determined that there is no item information in step S305, the error mail 119 is sent to the mail sender of the e-mail 103 (Sender in the SMTP header). ) Is transmitted to the sender, the sender can be warned when an inappropriate mail that does not include the case information is received.

  The mail content analysis unit 111 is executed after completion of the mail receiving unit 110, refers to the text described in the text of the email 103 or 104, determines whether this mail is registered, examined, or approved, It operates to set the approval flag to ON in the case of approval, and to turn on the write flag in the case of registration. In detail, as shown in FIG. 4, the format of the received e-mail is shown in FIG. Step S401 for determining whether or not the pattern matches the format pattern, and when it is determined that the pattern matches in Step S401, the mail content is analyzed based on the format pattern specification shown in FIG. ”(Depending on whether“ approval ”is included in the command word area) or not, in step S402, When the approval is determined, step S404 is executed to turn on the approval flag and end the processing, and when it is determined that the approval is not approved in step S402, the write flag is set to ON and the processing is ended to step S403. Thus, the approval flag can be set to ON in the case of approval, and the write flag can be set to ON in the case of registration.

  The authority control unit 112 is executed after the completion of the mail content analysis unit 111, acquires user information from the user master table 120 using the mail address to which the e-mail 103 or 104 is sent as a key, and the user information can be acquired. Or when the approval flag is ON, the user confirms whether or not the user has the authorization authority, and if there is a problem with any of them, the process is terminated and an email for sending back is returned. Further, when the transmitted email is an email sent from the system itself like the email 103, the above process is omitted.

  As shown in FIG. 5, the detailed operation of the authority control unit 112 refers to the sender (sender mail address) in the SMTP header of the e-mail to determine whether or not the system itself is the sender, and the system itself sends the sender. If it is determined in step S501 that the process is terminated, and if it is determined in step S501 that the system itself is not the sender, the user ID and authority information of the user is obtained from the user master table 120 using the sender mail address as a key. Step S502 to be acquired, whether or not the user acquired in Step S502 exists, Step S503 for ending the process when it is determined that the user does not exist, and Approval when it is determined that the user exists in Step S503 Determines whether the flag is ON, and terminates processing when it is determined that the flag is not ON Step S504, when it is determined in step S504 that the approval flag is ON, it is determined whether or not there is an approval authority for the business, and when it is determined that there is an approval authority, the process is terminated. When it is determined in step S505 that there is no approval authority, a mail for return can be returned by executing step S506 in which the error mail 119 is transmitted to the sender.

  The workflow control unit 113 is executed after the completion of the authority control unit 112, and the client 101 uses the screen to input a case name, a case content, etc. to the screen and performs registration. As shown in FIG. 6, step S601 writes the Message ID of the mail into the case table 117 using the case number of the email as a key. Similarly, the data content of the text part of the mail is stored in the case content table 118 using the case No as a key. Step S602 for writing, Step S603 for determining whether or not the approval flag of the transaction data is ON, and when it is determined that the approval flag is ON in Step S603, the item table 117 is referred to with the item number of the mail as a key. The workflow ID is acquired, and the acquired workflow ID The route ID is acquired from the route definition table 114 as a key, the next route ID is updated to the route ID of the matter table 117, and the workflow is advanced in step S604, and the route ID of the matter table 117 updated in step S604 is changed. Work that has been approved by acquiring the mail address from the user master 116 from the route definition table 114 as the key and using the route definition table 114 as a key and sending the e-mail 103 to the next processing vehicle. Can be registered by the electronic mail 103 to update the route ID and take over the work instruction for the next person in charge.
