How To Fix DMC_DTL049 - Semaphore values could not be determined and default values are taken

SAP Error Message - Details

• Message type: E = Error

• Message class: DMC_DTL - Messages for DMC data transfer layer

• Message number: 049

• Message text: Semaphore values could not be determined and default values are taken

What causes this issue?

The function that determines the possible data load for all the systems
involved in a data transfer (receiver, sender and conversion system)
detected that for at least one of these systems, the calculated load
number is 0.
This is an irregular situation, because in this case, no data transfer
would be possible.
Semphore value has been set to a default value of 50 for the respective
system.

System Response

This default value is a very high value and is set just to make sure
that we do not artificially slow down the transfer. The number of batch
jobs that really will be started will be limited by the number of
available batch jobs of the central system. But, here we run the risk
that the system for which the OS collector is not running will get too
much load.

How to fix this error?

There might be two reasons for this situation:
1) the necessary system information is missing in the respective
system. This happens if the OS collector does not run in this system.
Then, you need to start the OS collector in transaction ST06.
2) the percentage values specified are too low. In this case, change
these values.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
