<p><font size="2" face="sans-serif">Hi Loren,</font><br>
<br>
<font size="2" face="sans-serif">Yes, you are creating yourself a big problem here by configuring the same Prefix number 900.</font><br>
<font size="2" face="sans-serif">You should always configure a new unused (never before used) Prefix number when you create a new Development System and/or Client.</font><br>
<font size="2" face="sans-serif">You should maintain a list of used Prefix numbers in your SAP Landscape, and never reuse a Prefix number, even if you remove a System/Client.</font><br>
<br>
<font size="2" face="sans-serif">For example, you could configure your Prefix number for your new Client as follows:</font><br>
<br>
<font size="2" face="sans-serif">Prefix no. = 901</font><br>
<font size="2" face="sans-serif">SAP System = ED3</font><br>
<font size="2" face="sans-serif">Client = 100</font><br>

<font size="2" color="#1F497D" face="Calibri"> </font><br>
<font size="2" color="#1F497D" face="Calibri">Today, for the first time since this change was made, I needed to create a new standard task. So I defined the task and when I went to save it, I got an error message telling me the prefixes had not been defined in the client I was working in. So I went out to SWU3 and sure enough, the “Maintain Prefix Numbers” under definition environment had a red X:</font><br>

<font size="2" color="#1F497D" face="Calibri"> </font><br>
<font size="2" color="#1F497D" face="Calibri">So I launched the activity and I saw that there was an entry for the old 300 client in the table:</font><br>

<font size="2" color="#1F497D" face="Calibri"> </font><br>
<font size="2" color="#1F497D" face="Calibri">I then edited the entry (deleted and re-created it) for the new client 100:</font><br>

<font size="2" color="#1F497D" face="Calibri"> </font><br>
<font size="2" color="#1F497D" face="Calibri">I then went back to my new standard task and when I clicked “save”, it assigned a task number successfully. The problem is, I was expecting to get a task number up in the 400 range based on the last time I had to create a new task. But the task number that got created was 90000015:</font><br>

<font size="2" color="#1F497D" face="Calibri"> </font><br>
<font size="2" color="#1F497D" face="Calibri"> </font><br>
<font size="2" color="#1F497D" face="Calibri">I checked our QA and production systems and we do not already have a standard task 90000015 so I don’t think this newly generated task number is going to cause a problem. However, I am concerned about what is going to happen when I create my next task. Will it assign 90000016? We do already have a task with that number. Is the system going to be smart enough to find the next available number that has not already been used? Or have I created myself a big problem here by changing that prefix entry?</font><br>
