TELEGRAM APPROVAL PROCESS FLOW

---

1. The program will start a workflow with Task TS90000064.
2. The ZFM_TELE_CONFIRM_APRV function module will handle the Action Approval with input parameters ( DESCRIPTION[ ], WI_ID, CHAT_ID, DOC_NUM ).
3. The following are the two function modules where the function module will retrieve the WI_ID with the status “READY” as a value parameter:

• To transmit an approval decision to Telegram in HTML Script conversion with the parameters (DICKEY, WI ID, CHAT ID, DOC NUM) attached, use the ZFM_SEND_TELE1 function.
• When sending files to Telegram via the ZFM_SEND_FILES_TELE module function, ZFM_GET_ATTACHMENT is used to retrieve documents or attachments submitted to a program or workflow process. Below is an example of a Telegram output:

The user has the following action options after the approval notification enters Telegram to decide whether to approve:

Approve :

• The URL link that is embedded in the command button will be used to process the SAP CALL API, and a confirmation for the SAP API Call process and SAP Login access will then appear.

• If the login is successful, the server will use the SAP_WAPI_DECISION COMPLETE module function to perform the approve(dickey=1) decision by calling the ZCL_REST_GET_DICISION Module Class.

• When everything goes according to plan, the system will notify Telegram users that their request “has been approved.”

 

 

Reject :

• A confirmation for the SAP Call API procedure and SAP Login access will appear after the URL link that was placed in the command button has processed the SAP Call API.

• If the login process is successful, the server will make a call to the ZCL_REST_GET_DICISION Module Class, and if the user’s request is rejected (dickey=2), the system will send them a second notification in the form of a confirmation and ask for the explanation.

• After some specified time on the system, the Telegram API Call will be made with the URL https://api.telegram.org/bot<token>/getupdate to get back the Reason given by the user, then processed with the ZFM_GET_API_TELEGRAM function module where the data is in the form The JSON array will then be converted into an internal table in SAP using the following method:

• The SAP WAPI DECISION COMPLETE module function will carry out the division operation if the Reason has been provided.
• When the procedure is complete, the system will notify Telegram that the user “has been Reject.”
