Detailed Description and Symptoms
CPIC Error: max no of 100 conversions exceeded
There are two possibilities to solve the problem:
*) increasing the count of RFC connections. Sap note:314530
This could realize over the variable CPIC_MAX_CONV=500 (use a value you want). After changing this value you have to restart the SAP server!
Is SAP running on the same system as the Agent? If not, so be sure that the environment variable CPIC_MAX_CONV is also set on the agent's machine.
*) If you are not sure that all 100 batch processes comes from the SAP agent you could verify the batch processes connected to the SAP system with the transaction smgw.
Use the "Resources" on agent side (Systemoverview -> Agent -> Properties). Here it is possible to limit the resources of this agent to e.g. 40.
Now limit every SAP job to one resource. So you could start 40 SAP Jobs. New SAP jobs will wait until new resources are available.
