Production Support - Ticket Resolving

Note: For Previous posts refer the Archive link in this web page.
What is SAP Production Support - Ticket Resolving
1. How the tickets in production support are resolved?
2. Give some examples with solutions?
3. What are the types of ticket and its importance?
To answer these types of questions, read below.
Before going further, we need to know about SLA. What is SLA? SLA stands for Service Level Agreement. Imagine there is a software company Tech Sols limited which doing production support for a client is named Best Soaps Inc. Best Soaps Inc and Tech Sols will come to an agreement where they define expectations.
SLA defines the service agreement between Best Soaps Inc and Tech Sols. For example the document defines the time frame to solve the different types of problem tickets.
What happens if the Tech sols could not solve a problem occurred in the Production as per the agreement? Best soaps Inc will impose penalty on Tech sols. All these terms and conditions will be defined during SLA preparation
The severity of the Problem Tickets depends on the SLA. It can be like:
1. Critical. 2. Urgent. 3. High. 4. Medium 5. Low
The response times and resolution times again are defined in the SLA based on the clients requirement and the charges.
This is probably from the viewpoint of Criticality of the problem faced by the client as defined by SAP.
1) First Level Ticketing:
Not severe problem. Routine errors. Mostly handled by Service desk arrangement of the company (if have one).
Eg: a) Say Credit limit block in working on certain documents? b) Pricing Condition Record not found even though conditions are maintained? c) Unable to print a delivery document or Packing list?
PS: In the 4th phase of ASAP Implementation Methodology (i.e. Final Preparations for GO-LIVE) SAP has clearly specified that a Service desk needs to be arranged for any sort of Implementation for better handling of Production errors.
Service desk lies with in the client.
2) Second Level Ticketing:
Some sort of serious problems. Those could not be solved by Service Desk. Should be referred to the Service Company (or may be company as prescribed in SLA).
Eg: a) Credit Exposure (especially open values) doesn't update perfectly to KNKK Table. b) Inter company Billing is taking a wrong value of the Bill. c) Need a new order type to handle reservation process d) new product has been added to our selling range. Need to include this into SAP. (Material Masters, Division attachments, Stock Handling etc.)
3) Third Level Ticketing:
Problems could not be solved by both of the above, are referred to Online Service Support (OSS) of SAP Itself. SAP tries to solve the Problem, sometimes by providing the perfect OSS Notes, fits to the error and rarely SAP logs into our Servers (via remote log-on)for post mortem the problem. (The Medical check-up client, connections, Login id and Passwords stuff are to be provided to SAP whenever they need or at the time of opening OSS Message.)
There are lots of OSS Notes on each issue, SAP Top Notes and Notes explaining about the process of raising a OSS Message.
Sometimes SAP Charges to the client / Service Company depending on the Agreement made at the time of buying License from SAP.
Eg: 1) Business Transition for the Currency 'EUR' is not possible. Check OSS Note - This comes at the time of making Billing. 2) Transaction MMPI- Periods cannot be opened – See OSS Note.
There are many other examples on the issue.
4) Fourth Level Ticketing:
Where rarely, problems reach this level.
Those problem needs may be re-engineering of the business process due to change in the Business strategy. Up gradation to new Version. More or less this leads to extinction of the SAP Implementation.
Note: In real time you will be provided with OSS notes Log in ID and password. With the help of that user ID and password you can login to the URL service.sap.com and search for OSS notes.
